prepared in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all of the information
and notes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments, consisting
of normal recurring accruals, considered necessary for a fair presentation have
been included. Operating results for the period ended April 2, 2005 are not
necessarily indicative of the results that may be expected for the year ending

2. BUSINESS SEGMENT INFORMATION

The Company designs, manufactures and sells circuit protection devices
throughout the world. The Company has three reportable geographic segments:
Americas, Europe and Asia-Pacific. The circuit protection market in these
geographical segments is categorized into three major product areas: electronic,
automotive and electrical.

The Company evaluates the performance of each geographic segment based on its
sales and net income or loss. The Company accounts for intersegment sales as if
the sales were to third parties. The Company's reportable segments are the
geographical regions where the revenue is earned and expenses are incurred. The
Company has subsidiaries in Americas, Europe and Asia-Pacific.

Revenues from no single customer amounted to 10% or more of the Company's total
revenues for the quarter ended April 2, 2005.

Information concerning the operations in these geographic segments for the

Options to purchase 518,100 and 252,204 shares of common stock were outstanding
at April 2, 2005, and April 3, 2004, respectively, but were not included in the
computation of diluted earnings per share because the options' exercise prices
were greater than the average market price of the common shares and, therefore,
the effect would be anti-dilutive.

6. HEINRICH ACQUISITION

On May 6, 2004, the Company acquired 82% of the common stock of Heinrich
Industrie AG ("Heinrich") for Euro 39.5 million (approximately $47.1 million) in
cash and acquisition costs of approximately $1.8 million. The Company purchased
the controlling interest in Heinrich from its two largest shareholders and
initiated a tender offer for the remaining shares of the publicly held company.
The Company funded the acquisition with $17.5 million in cash and $32.0 million
of borrowings on an existing revolving line of credit.

Subsequent to May 6, 2004, the Company purchased additional shares of Heinrich
stock for approximately $8.7 million, bringing the total ownership to 97.2% as
of April 2, 2005.

Heinrich is the holding company for the Wickmann Group of circuit protection
products, which has three business units: electronic, automotive and electrical.
Littelfuse has continued to operate Heinrich in such business units subsequent
to the acquisition. The Heinrich acquisition expands the Company's product
offering and strengthens the Company's position in the circuit protection
industry.


                                       7

The acquisition was accounted for using the purchase method of accounting and
the operations of Heinrich are included in the Company's operations from the
date of acquisition. The following table sets forth the purchase price
allocation for the acquisition of Heinrich in accordance with the purchase
method of accounting with adjustments to record the acquired assets and
liabilities of Heinrich at their estimated fair market or net realizable values.

7. DERIVATIVES AND HEDGING

On June 11, 2002, the Company, entered into cross-currency rate swaps, with a
notional amount of $11.6 million, as a cash flow hedge of the variability of Yen
cash flows attributable to the USD/JPY exchange rate risk on forecasted




                                       8


intercompany sales of inventory to a Japanese subsidiary. The cross-currency
swaps convert $11.6 million of the Company's fixed rate 6.16% U.S. Dollar debt
to fixed rate 3.13% Japanese Yen debt. At the inception of the hedge, both the
foreign currency swap and the intercompany sales subject to the hedge were
denominated in Japanese Yen. The swap agreements are accounted for as a cash
flow hedge and reported at fair value. The notional amount outstanding at April
2, 2005, was $2.1 million and the fair value of the outstanding cross-currency
rate swap agreements was recognized as a $0.3 million liability in the accrued
liabilities on the consolidated balance sheet. The change in the liability has
been reflected as a charge to shareholders' equity in the consolidated balance
sheet at April 2, 2005. The Company's hedges are considered effective and the
net gain or loss from hedge ineffectiveness was not material.

For the period from June 1, 2004, to September 30, 2005, Heinrich Industrie AG
purchased Euro forward contracts that hedge the variability of U.S. Dollar cash
attributable to the exchange rate risk on forecasted intercompany sales to U.S.
and Asian subsidiaries. These forward contracts guarantee the rate at which the
U.S. Dollar cash flows will be converted to Euro in the future. The forward
agreements are reported at the fair value and recorded as an asset under Other
Assets on the consolidated balance sheet at April 2, 2005. The gains since the
date of the Heinrich acquisition were recognized in the income statement and
were immaterial.

Derivative financial instruments involve, to a varying degree, elements of
market and credit risk not recognized in the consolidated financial statements.
The market risk associated with these instruments resulting from interest rate
movements is expected to offset the market risk of the underlying transactions
being hedged. The counterparties to the agreements relating to the Company's
cross-currency rate instruments consist of major international financial
institutions with high credit ratings. The Company does not believe that there
is significant risk of non-performance by these counterparties because the
Company monitors the credit ratings of such counterparties, and limits the
financial exposure and amount of agreements entered into with any one financial
institution. While the notional amount of the derivative financial instruments
provide one measure of the volume of these transactions, they do not represent
the amount of the Company's exposure to credit risk. The amounts potentially
subject to credit risk (arising from the possible inability of counterparties to
meet the terms of their contracts) are generally limited to the amounts, if any,
by which the counterparties' obligations under the contracts exceed the
obligations of the Company to the counterparty.

9. COMPREHENSIVE INCOME

Total comprehensive income for the three months ended April 2, 2005, and April
3, 2004, was approximately $0.9 million and $9.3 million, respectively. The
adjustment for comprehensive income consists of deferred gains and losses from
foreign currency translation adjustments and qualified cash flow hedges for the
periods ended April 2, 2005, and April 3, 2004, and unrealized gains and losses
on available-for-sale securities for the period ended April 2, 2005.

11. RECENT ACCOUNTING PRONOUNCEMENTS

In December 2004, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standard (SFAS) No. 123R, "Share-Based
Payment," replacing SFAS No. 123 and superseding Accounting Principles Board
(APB) Opinion No. 25. SFAS 123R requires public companies to recognize
compensation expense for the cost of awards of equity compensation. This
compensation cost will be measured as the fair value of the award estimated
using an option-pricing model on the grant date. The provisions of SFAS No. 123R
were to become effective at the beginning of the first interim or annual period
beginning after June 15, 2005. On April 14, 2005, the Securities and Exchange
Commission adopted a staff recommendation to delay the effective date for public
companies to the first interim or annual reporting period of a registrant's
first fiscal year beginning on or after December 15, 2005.

As permitted by Statement 123, the Company currently accounts for share-based
payments to employees in accordance with APB No. 25, "Accounting for Stock
Issued to Employees", using the intrinsic value method. The Company expects to
adopt Statement 123R at the beginning of fiscal year 2006. The Company is
currently evaluating the various transition provisions under provisions under
SFAS 123R. The adoption of Statement 123R is expected to result in increased
compensation expense in future periods.

Results of Operations
First Quarter, 2005

Sales increased $10.3 million or 9% to $121.7 million in the first quarter of
2005, compared to $111.4 million in the first quarter of 2004 due to the
acquisition of Heinrich. Excluding Heinrich, sales for the first quarter of 2005
decreased approximately 11% compared to the prior year quarter primarily due to
a slowdown in the electronics business.

On a geographic basis, sales in the Americas decreased $3.0 million or 6% in the
first quarter of 2005, compared to the first quarter of last year. The
electronics business was the main contributor to this decline as sales to North
American distributors and telecom OEM accounts slowed during the current
quarter. Heinrich contributed $1.5 million in the Americas for the quarter.
Europe sales increased $13.6 million or 65% in the first quarter of 2005
compared to the first quarter of 2004. Heinrich contributed $16.8 million in
Europe for the quarter. Excluding Heinrich, Europe sales decreased $3.2 million
or 15% compared to the first quarter of 2004 due to weakened demand for
electronics products partially offset by favorable currency effects of $0.8
million. Asia sales decreased $0.3 million or 1% compared to the prior year
first quarter. Excluding Heinrich, which contributed $4.3 million, Asia sales
decreased $4.6 million or 12% compared to the first quarter of 2004. This
decrease was due to inventory correction at electronic distributors as well as
weaker demand in the China telecom market.

Electronic sales, excluding Heinrich, decreased $11.6 million or 16% for the
first quarter of 2005 compared to the prior year quarter due to distributor
inventory correction and softening in telecom end markets. Automotive sales,
excluding Heinrich, decreased $2.0 million or 7% for the first quarter of 2005
compared to the prior year quarter. Automotive sales for the first quarter of
2005 were unfavorably impacted by lower car build in North America and


                                       11


Europe, and the prior year quarter benefited from incremental sales related to a
vehicle recall program. Electrical sales, excluding Heinrich, increased $1.3
million or 15% in the first quarter of 2005 compared to the same quarter last
year as the electrical markets benefited from increased industrial manufacturing
activity and the beginnings of a rebound in non-residential construction.

Gross profit was $39.7 million or 32.6% of sales for the first quarter of 2005,
compared to $39.8 million or 35.7% in the same quarter last year. The decrease
in gross margin was mainly attributable to reduced operating leverage from lower
sales, $1.1 million of severance charges related to reductions in force and the
addition of lower margin Heinrich sales.

Total operating expense was $32.5 million or 26.7% of sales for the first
quarter of 2005 compared to $24.1 million or 21.6% of sales for the same quarter
in the prior year. The increase in operating expense reflects the acquisition of
Heinrich, additions to sales and engineering staffs to support the Company's
solution selling strategy and $0.5 million of severance charges in the current
quarter related to staffing reductions.

Operating income was $7.2 million or 5.9% of sales for the first quarter of 2005
compared to $15.7 million or 14.1% of sales for the same quarter of last year
reflecting the lower sales and increased costs discussed above.

Interest expense was $0.5 million in the first quarter of this year compared to
$0.4 million in the first quarter of last year. Other income was $0.1 million
for the first quarter of 2005 compared to other expense of $0.3 million in the
first quarter of last year, due to current year other income of $0.1 million
from Heinrich and lower other expenses in the current year.

Income before income taxes and minority interest was $6.9 million for the first
quarter 2005 compared to $15.0 million for the first quarter of 2004. Income
taxes were $2.4 million with an effective tax rate of 35% for the first quarter
of 2005 compared to $5.4 million with an effective tax rate of 36% in the first
quarter of last year.

Net income for the first quarter 2005 was $4.4 million or $0.20 per diluted
share compared to $9.6 million or $0.43 per diluted share for the same quarter
of last year.


Liquidity and Capital Resources

Assuming no material adverse changes in market conditions or interest rates,
management expects that the Company will have sufficient cash from operations to
support both its operations and its current debt obligations for the foreseeable
future.

Littelfuse started the 2005 year with $28.6 million of cash and cash
equivalents. Net cash provided by operations was $0.1 million for the first
three months. Net cash provided by operations includes net income of $4.4
million, depreciation of $6.6 million and amortization of $0.6 million in
addition to various working capital and other items. Accounts receivable
increased $1.5 million and inventory decreased $0.9 million. Accounts payable,
accrued expenses, prepaid expenses and other items unfavorably impacted net cash
provided by operations by $11.0 million, primarily due to the payment of 2004
accrued bonuses of approximately $7.0 million and a $2.1 million increase in
prepaid assets. Net cash used in investing activities included $8.7 million in
net purchases of property, plant and equipment. In addition, net cash provided
by financing activities included stock option exercises of $0.5 million along
with net proceeds of long-term debt of $9.8 million, notes receivable payback of
$3.5 million and the offsetting purchase of treasury stock for $3.2 million. The
effects of exchange rate changes decreased cash by $1.2 million. The net cash
provided by operations, less investing and financing activities plus the effects
of exchange rate changes, resulted in a $0.8 million net increase. This left the
Company with a cash balance of $29.4 million at April 2, 2005.

The ratio of current assets to current liabilities was 1.8 to 1 at the end of
the first quarter of 2005 compared to 2.0 to 1 at the end of the first quarter
2004. The days sales in receivables was approximately 58 days at the end of the
first quarter of 2005, compared to 57 days at the end 2004 and 49 days at the
end of the first quarter 2004. The increase in days sales in receivables from
the first quarter of the prior year was due primarily to the elimination of
early payment discounts for certain distributors and the addition of Heinrich,
whose days sales in receivables is higher than that of Littelfuse. The days
inventory outstanding was approximately 85 days at the end of the first quarter
of 2005 compared to 91 days at the end of 2004 and 69 days at end of the first
quarter of 2004. The decrease in days



                                       12

inventory outstanding from the end of 2004 resulted primarily from improved
inventory management. The increase in days inventory outstanding from the first
quarter of the prior year was due to the addition of Heinrich, whose days
inventory outstanding is higher than that of Littelfuse and lower sales in the
first quarter of 2005.

The Company's capital expenditures, net of cash from asset sales, were $8.7
million for the first quarter of 2005 compared to $3.0 million for the first
quarter of 2004 due to spending in the most recent quarter related to
manufacturing process improvements, new product introductions and future
capacity expansions.

Total debt, including the current portion, at the end of the first quarter 2005
totaled $43.9 million and consisted of the following: (1) 6.16% private
placement notes totaling $10.0 million, (2) foreign revolver borrowings totaling
$6.4 million and (3) credit revolver borrowings totaling $27.5 million. Of this
indebtedness, $42.6 million is considered to be current liabilities. The Company
has a $50.0 million, three-year revolving bank credit agreement that expires on
August 26, 2006. The bank credit agreement is subject to a maximum indebtedness
calculation and other financial covenants. At April 2, 2005, the Company had
available $22.5 million of borrowing capability under the revolving bank credit
agreement. The revolving bank credit agreement has an interest rate of prime or
LIBOR plus 0.875%. The Company also had $2.5 million in letters of credit
outstanding at April 2, 2005.

Item 3.  Quantitative and Qualitative Disclosures about Market Risk

The Company is exposed to market risk from changes in foreign exchange rates,
commodities and, to a lesser extent, interest rates. Management believes that
the Company's exposure to these risks is immaterial and not significant enough
to warrant disclosure of quantitative information regarding market risk.

The Company had $43.9 million of long-term debt outstanding at April 2, 2005,
primarily in the form of senior notes and lines of credit. Approximately 23% of
the Company's long-term debt is at fixed rates.

A portion of the Company's operations consists of manufacturing and sales
activities in foreign countries. The Company has foreign manufacturing
facilities in the U.S., Mexico, England, Ireland, China, Germany and the
Philippines. Substantially all sales in Europe are denominated in Euro, U.S.
Dollar and British Pound Sterling, and substantially all sales in the
Asia-Pacific region are denominated in U.S. Dollar, Japanese Yen and South
Korean Won.

The Company's identifiable foreign exchange exposures result from the purchase
and sale of products from affiliates, repayment of intercompany trade and loan
amounts and translation of local currency amounts in consolidation of financial
results. Changes in foreign currency exchange rates or weak economic conditions
in the foreign countries in which it manufactures and distributes products could
affect the Company's sales, accounts receivable values and financial results.
The Company uses netting and offsetting intercompany account management
techniques to reduce known foreign currency exposures deemed to be material. The
Company utilizes derivative instruments as hedges of specific foreign currency
cash flows when appropriate.



                                       13



The Company has entered into cross-currency rate swaps with a notional amount of
$11.6 million. The cross-currency swaps convert $11.6 million of the Company's
fixed rate 6.16% U.S. dollar debt to fixed rate 3.13% Japanese Yen debt. At the
inception of the hedge, both the foreign currency swap and the intercompany
sales subject to the hedge were denominated in Japanese Yen. The fair value of
the rate swap agreements outstanding at April 2, 2005, which had a notional
amount of $2.1 million, was recognized as a $0.3 million liability, and is
reported in consolidated shareholders' equity as a component of other
comprehensive income.

For the period from June 1, 2004, to September 30, 2005, Heinrich Industrie AG
purchased Euro forward contracts that hedge the variability of U.S. Dollar cash
attributable to the exchange rate risk on forecasted intercompany sales to U.S.
and Asian subsidiaries. These forward contracts guarantee the rate at which the
U.S. Dollar cash flows will be converted to Euros in the future. The forward
agreements are reported at the fair value and recorded as an asset under Other
assets on the consolidated balance sheet at April 2, 2005. The gains since the
date of the Heinrich acquisition were recognized in the income statement and
were immaterial.

A risk management policy has been implemented by the Company that establishes
the procedures and controls over derivative financial instruments. Under the
policy, the Company does not use derivative financial instruments for trading
purposes and the use of such instruments is subject to the approval of senior
officers. Typically, the use of such derivative instruments is limited to
hedging activities related to specific foreign currency cash flows. The
Company's exposure related to such transactions is, in the aggregate, not
material to the Company's financial position, results of operations and cash
flows.

The Company uses various metals in the production of its products, including
zinc, copper and silver. The Company's earnings are exposed to fluctuations in
the prices of these commodities. The Company does not currently use derivative
financial instruments to mitigate this commodity price risk.

Item 4.  Controls and Procedures

As of April 2, 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 Company's Chief Executive
Officer and Chief Financial Officer. The Company's management believes that the
material weaknesses discussed in the Company's Annual Report on Form 10-K for
the fiscal year ended January 1, 2005 relating to the approval process over
journal entries and lack of adequate controls over the accounting for foreign
currency translations have been eliminated.
