ELECTRONIC PRODUCTS

Electronic circuit protection products are used to protect circuits in a
multitude of electronic systems. The Company's product offering includes a
complete line of overcurrent and overvoltage solutions including: (1) fuses and
protectors, (2) positive temperature coefficient, (PTC) resettables, (3)
varistors, (4) electrostatic discharge (ESD) suppressors, (5) discrete transient
voltage suppression (TVS) diodes, TVS diode arrays and protection thyristors,
(6) gas discharge tubes, (7) power switching components, and (8) fuseholders,
blocks and other.

2



Electronic fuses and protectors are devices that contain an element which melts
in an overcurrent condition. Electronic miniature and subminiature fuses are
designed to provide circuit protection in the limited space requirements of
electronic equipment. The Company's fuses are used in a wide variety of
electronic products, including wireless telephones, consumer electronics,
computers, modems and telecommunications equipment. The Company markets these
products under the following trademarked and brand names: PICO(R) II and NANO2
(R) SMF.

Resettables are positive temperature coefficient (PTC) polymer devices that
limit the current when an overcurrent condition exists and then reset themselves
once the overcurrent condition has cleared. The Company's product line offers
both radial leaded and surface mount products.

Varistors are ceramic-based high-energy absorption devices that provide
transient overvoltage and surge suppression for automotive, telecommunication,
consumer electronics and industrial applications. The Company's product line
offers both radial leaded and multilayer surface mount products.

Electrostatic discharge (ESD) suppressors are polymer-based devices that protect
an electronic system from failure due to rapid transfer of electrostatic charge
to the circuit. The Company's PulseGuard(R) line of ESD suppressors is used in
PC and PC peripherals, digital consumer electronics and wireless applications.

Discrete diodes, diode arrays and protection thyristors are fast switching
silicon semiconductor structures. Discrete diodes protect a wide variety of
applications from overvoltage transients such as ESD, inductive load switching
or lightning, while diode arrays are used primarily as ESD suppressors.
Protection thyristors are commonly used to protect telecommunications circuits
from overvoltage transients such as those resulting from lightning. Applications
include telephones, modems, data transmission lines and alarm systems. The
Company markets these products under the following trademarked brand names:
TECCOR(R), SIDACtor(R) and Battrax(R).

Gas discharge tubes are very low capacitance devices designed to suppress any
transient voltage event that is greater than the breakover voltage of the
device. These devices are primarily used in telecom interface and conversion
equipment applications as protection from overvoltage transients such as
lightning.

Power switching components are used to regulate energy to various type loads
most commonly found in industrial and home equipment. These components are
easily activated from simple control circuits or interfaced to computers for
more complex load control. Typical applications include heating, cooling,
battery chargers and lighting.

In addition to the above products, the Company is also a supplier of fuse
holders (including OMNI-BLOK(R)), fuse blocks and fuse clips primarily to
customers that purchase circuit protection devices from the Company.

AUTOMOTIVE PRODUCTS

Fuses are extensively used in automobiles, trucks, buses and off-road equipment
to protect electrical circuits and the wires that supply electrical power to
operate lights, heating, air conditioning, radios, windows and other controls.
Currently, a typical automobile contains 30 to 100 fuses, depending upon the
options installed. The fuse content per vehicle is expected to continue to grow
as more electronic features are included in automobiles. The Company also
supplies fuses for the protection of electric and hybrid vehicles.

The Company is a primary supplier of automotive fuses to United States, Asian
and European automotive OEMs, automotive component parts manufacturers and
automotive parts distributors. The Company also sells its fuses in the
replacement parts market, with its products being sold through merchandisers,
discount stores and service stations, as well as under private label by national
firms. The Company invented and owns most of the U.S. patents related to the
blade type fuse which is the standard and most commonly used fuse in the
automotive industry. The Company's automotive fuse products are marketed under
the following trademarked brand names: ATO(R), MINI(R), MAXI(TM), MIDI(R),
MEGA(TM) and CablePro(TM).

A majority of the Company's North American automotive fuse sales are made to
wire harness manufacturers that incorporate the fuses into their products. The
remaining automotive fuse sales are made directly to automotive manufacturers
and through distributors who in turn sell most of their products to automotive
product wholesalers, such as warehouse distributors, discount stores and service
stations.

The Company has licensed its patented MINI(R) and MAXI(TM) automotive fuse
designs to Bussmann, a division of Cooper Industries. Bussmann is the Company's
largest domestic competitor. Additionally, the Company has entered into a
licensing agreement with Pacific Engineering Company, Ltd., a Japanese fuse
manufacturer, which produces and distributes the Company's

3



patented MINI(R) fuses to Asian automotive OEMs and wire harness manufacturers.
See "Business - Patents, Trademarks and Other Intellectual Property" and "-
Competition."

ELECTRICAL PRODUCTS

The Company entered the electrical market in 1983 and manufactures and sells a
broad range of low-voltage and medium-voltage circuit protection products to
electrical distributors and their customers in the construction, original
equipment manufacturers ("OEM") and industrial maintenance and repair operations
("MRO") markets.

Power fuses are used to protect circuits in various types of industrial
equipment and circuits in industrial plants, office buildings and residential
units. They are rated and listed under one of many Underwriters' Laboratories
fuse classifications. Major applications for power fuses include protection from
over-load and short-circuit currents in motor branch circuits, heating and
cooling systems, control systems, lighting circuits and electrical distribution
networks.

The Company's POWR-GARD(R) product line features the Indicator(TM) series power
fuse used in both the OEM and MRO markets. The Indicator(TM) technology provides
visual blown fuse indication at a glance, reducing maintenance and downtime on
production equipment. The Indicator(TM) product offering is widely used in motor
protection and industrial control panel applications.

PRODUCT DESIGN AND DEVELOPMENT

The Company employs scientific, engineering and other personnel to continually
improve its existing product lines and to develop new products at its research
and engineering facilities in Des Plaines, Illinois, Irving, Texas, Swindon, UK,
Witten and Dunsen, Germany and Dundalk, Ireland. The Product Technology
Department maintains a staff of engineers, chemists, material scientists and
technicians whose primary responsibility is the design and development of new
products.

Proposals for the development of new products are initiated primarily by sales
and marketing personnel with input from customers. The entire product
development process ranges from several months to 18 months based on complexity
of development with continuous efforts to reduce the development cycle. During
fiscal years 2004, 2003 and 2002, the Company expended $17.6 million, $8.7
million and $8.3 million, respectively, on product design and development.

PATENTS, TRADEMARKS AND OTHER INTELLECTUAL PROPERTY

The Company generally relies on patent and trademark laws and license and
nondisclosure agreements to protect intellectual property and proprietary
products. In cases where it is deemed necessary by management, key employees are
required to sign an agreement that they will maintain the confidentiality of the
Company's proprietary information and trade secrets. This information, for
business reasons, is not disclosed to the public.

As of January 1, 2005, the Company owned 162 patents in North America, 70
patents in the European Economic Community and 25 patents in other foreign
countries. The Company has also registered trademark protection for certain of
its brand names and logos. The 162 North American patents are in the following
product categories: 109 electronic, 26 automotive, 27 electrical .

New products are continually being developed to replace older products. The
Company regularly applies for patent protection on such new products. Although
in the aggregate the Company's patents are important in the operation of its
businesses, the Company believes that the loss by expiration or otherwise of any
one patent or group of patents would not materially affect its business.

The Company currently licenses its MINI(R) and MAXI(TM) automotive fuse
technology to Bussmann, a division of Cooper Industries and the Company's
largest domestic competitor. The license granted in 1987 is nonexclusive and
grants the Company the right to receive royalties of 4% of the licensee's
revenues from the sale of the licensed products with an annual minimum of
$25,000. This license expires upon the expiration of the licensed product
patents.

In addition, a second license covering the MINI(R) fuse technology was granted
to Pacific Engineering Company, Ltd., a Japanese manufacturer that produces and
distributes the Company's patented automotive fuses to Asian-based automotive
OEMs and wire harness manufacturers. The license provides the Company with
royalties of 2.5% of the licensee's revenues from the sale of the licensed
products, with an annual minimum of $100,000. This second license expires on
April 6, 2006.

License royalties amounted to $0.5 million, $0.4 million and $0.4 million for
fiscal 2004, 2003 and 2002, respectively.

MANUFACTURING

The Company performs the majority of its own fabrication and stamps some of the
metal components used in its fuses, holders and switches from raw metal stock
and makes its own contacts and springs. In addition, the Company fabricates
silicon wafers for certain applications and performs its own plating (silver,
nickel, zinc, tin and oxides). All thermoplastic molded component requirements
used for such products as the ATO(R), MINI(R) and MAXI(TM) fuse product lines
are met through the Company's in-house molding capabilities.

After components are stamped, molded, plated and readied for assembly, final
assembly is accomplished on fully automatic and semi-automatic assembly
machines. Quality assurance and operations personnel, using techniques such as
Statistical Process Control, perform tests, checks and measurements during the
production process to maintain the highest levels of product quality and
customer satisfaction.

The principal raw materials for the Company's products include copper and copper
alloys, heat resistant plastics, zinc, melamine, glass, silver, raw silicon,
solder and various gases. The Company depends upon a sole source for several
heat resistant plastics and zinc. The Company believes that suitable alternative
heat resistant plastics and zinc are available from other sources at prices that
would not have a material adverse effect on the Company. All of the other raw
materials are purchased from a number of readily available outside sources.

A computer-aided design and manufacturing system (CAD/CAM) expedites product
development and machine design and our laboratories test new products, prototype
concepts and production run samples. The Company participates in "Just-in-Time"
delivery programs and with many of its major suppliers and actively promotes the
building of strong cooperative relationships with its suppliers by utilizing
Early Supplier Involvement techniques and involving them in pre-engineering
product and process development.

ITEM 9A. CONTROLS AND PROCEDURES

DISCLOSURE CONTROLS AND PROCEDURES

The Company maintains disclosure controls and procedures that are designed to
ensure that information required to be disclosed in the Company's Exchange Act
reports is recorded, processed, summarized and reported within the time periods
specified in the Securities and Exchange Commission's rules and forms, and that
such information is accumulated and communicated to the Company's management,
including the Chief Executive Officer and Chief Financial Officer, as
appropriate, to allow timely decisions regarding required disclosure.

As of the end of the period covered by this Annual Report on Form 10-K for
January 1, 2005, the Chief Executive Officer and Chief Financial Officer of the
Company evaluated the effectiveness of the disclosure controls and procedures of
the Company and concluded that these disclosure controls and procedures are
effective to ensure that material information relating to the Company and its
consolidated subsidiaries has been made known to them by the employees of the
Company and its consolidated subsidiaries during the period preceding the
filing of this Report. There were no significant changes in the Company's
internal controls during the period covered by this Report that could materially
affect these controls or could reasonably be expected to materially affect the
Company's internal control reporting, disclosures and procedures subsequent to
the last day they were evaluated by the Chief Executive Officer and Chief
Financial Officer of the Company.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Littelfuse, Inc. is responsible for establishing and
maintaining adequate internal control over financial reporting as such term is
defined in Exchange Act Rules 13a-15(f) and 15d-(f). Littelfuse, Inc.'s internal
control system was designed to provide reasonable assurance to the Company's
management and the Board of Directors regarding the preparation and fair
presentation of published financial statements.

All internal control systems, no matter how well designed, have inherent
limitations. Therefore, even those systems determined effective can provide only
reasonable assurance with respect to financial statement preparation and
presentation.

An internal control significant deficiency is a control deficiency, or
combination of control deficiencies, that adversely affects the company's
ability to initiate, authorize, record, process, or report external financial
data reliably in accordance with generally accepted accounting principles such
that there is more than a remote likelihood that a misstatement of the company's
annual or interim financial statements that is more than inconsequential will
not be prevented or detected. An internal control material weakness is a
significant deficiency, or combination of significant deficiencies, that results
in more than a remote likelihood that a material misstatement of the annual or
interim financial statements will not be prevented or detected.

Littelfuse, Inc.'s management assessed the effectiveness of the Company's
internal control over financial reporting as of January 1, 2005 based upon the
framework in Internal Control - Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). This assessment
identified material weaknesses in the Company's approval process over journal
entries and a lack of adequate controls over the accounting for foreign currency
translations. Specifically, certain managers had the ability to record journal
entries of significant amounts in the Company's consolidation process without
adequate review or supporting documentation. Additionally, a number of
adjustments to the amounts reported in the Consolidated Balance Sheet and
Statement of Cash Flows were needed due to the failure and lack of controls
mentioned above. The Company recorded an adjustment to increase both accrued
liabilities and inventory without adequate support review that was subsequently
corrected after it was determined it was recorded in error. The increase in
accrued liabilities should have been an increase to foreign currency
translation. Additionally, two significant adjustments were made to correct the
amount reported as "Effect of exchange rate changes in cash" in the consolidated
statements of Cash Flows, which impacted cash flows from operating activities
and cash flows from financing activities.

Because of the material weaknesses described above, management concluded that,
as of January 1, 2005, the Company's internal control over financial reporting
was not effective based on those criteria.

Littelfuse, Inc.'s independent registered public accounting firm, Ernst & Young
LLP, has issued an audit report on our assessment of the Company's internal
control over financial reporting and the effectiveness of the Company's internal
control over financial reporting. Their report appears on page 24 of the Annual
Report in Exhibit 13.1.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

There was no change in the Company's internal control over financial reporting
that occurred during the Company's most recent fiscal quarter that has
materially affected, or is reasonably likely to materially affect, the Company's
internal control over financial reporting.

REMEDIATION STEPS TO ADDRESS MATERIAL WEAKNESS

The company has implemented the following remediation steps to address the
material weakness discussed above:

- - Additional procedures have been implemented over the journal entry
approval process.

- - The Company will hire additional financial reporting personnel who have
relevant experience with foreign currency translation.

- - Additional procedures will be implemented to review on a quarterly basis
the foreign currency translation component of accumulated comprehensive
income and the impact of foreign exchange on cash and cash equivalents.
