               LITTELFUSE REPORTS THIRD QUARTER FINANCIAL RESULTS

         DES PLAINES, ILLINOIS, NOVEMBER 2, 2006 - Littelfuse, Inc.
(NASDAQ/NGS:LFUS) today reported results for the third quarter of 2006.

Third Quarter Highlights

- -    Sales of $143.4 million for the third quarter of 2006 were up 17% compared
     to the prior-year quarter. Sales increased in all geographic areas, with
     particular strength in Asia. Electronics end-markets were the primary
     contributors to the growth, while the electrical business grew modestly and
     automotive was flat.

- -    Diluted earnings per share were $0.42 for the third quarter of 2006
     compared to $0.17 per diluted share for the third quarter of 2005. Earnings
     for the third quarter of 2006 included pre-tax charges of $3.9 million (or
     approximately $0.12 per share after tax) related to the last phase of the
     Heinrich consolidation. These charges included $2.3 million of accrued
     employee-related cost pursuant to contract obligations and $1.6 million of
     non-cash asset impairment charges.

- -    The effective tax rate for the third quarter of 2006 was 22%, due to a $1.2
     million favorable tax reserve adjustment that reduced the effective tax
     rate by 10 percentage points.

- -    Adjusted diluted earnings per share (see Supplemental Information schedule)
     were $0.48. This excludes the Heinrich charges and the one-time tax benefit
     mentioned above.

- -    Adjusted operating margin (see Supplemental Information schedule) was 11.3%
     for the third quarter of 2006, compared to adjusted operating margin of
     8.1% for the third quarter of 2005 and adjusted operating margin of 12.4%
     for the second quarter of 2006.

- -    Another strong cash flow quarter brought year-to-date cash flow from
     operating activities to $54.4 million. This has more than funded the $14.1
     million in capital expenditures and four acquisitions totaling $37.6
     million. Cash flow for the year 2006 is expected to be a Littelfuse record.

- -    The book-to-bill ratio for electronics for the third quarter of 2006 was
     .91. This is down from 1.03 for the second quarter and 1.17 for the first
     quarter.

- -    Overall capacity utilization for electronics held steady at about 85%, with
     Teccor also continuing at about 85%.

Third Quarter Operating Results

         The strong sales growth for the quarter and year to date has been
driven largely by the electronics business, which has performed well across all
geographies and all end-markets. However, the declining electronics book-to-bill
ratio indicates that these markets are slowing down. The electrical business
continues to grow steadily, while automotive has weakened and was flat for the
quarter.

         "It was another good quarter for Littelfuse," said Gordon Hunter, Chief
Executive Officer. "We posted solid financial results and made excellent
progress on integrating our recent acquisitions and transitioning several
manufacturing operations to Asia. However, it is now becoming clear that our
electronic sales growth of 22% so far this year has outpaced the end-market
growth and resulted in some inventory build at distributors, contract
manufacturers and OEMs. Thus, the inventory correction, which we mentioned as a
possibility three months ago, now seems more certain."

         "As expected, our adjusted operating margin for the third quarter
declined sequentially due to higher commodity prices, as well as higher costs
related to acquisition integration and plant and warehouse consolidation
activities," said Phil Franklin, Chief Financial Officer. "We have implemented
price increases that will partially offset the higher commodity prices, but
because of existing contracts, some of the largest increases will not take
effect until early next year."

         "The next few quarters will be bumpy as we work through the electronics
inventory correction and complete a number of acquisition integrations and
manufacturing transitions," said Hunter.

Fourth Quarter Outlook

     -   Fourth quarter sales now look like they will be down at least 10%
         sequentially, and maybe as much as 15%, reflecting an electronics
         inventory correction on top of the normal fourth quarter seasonal
         decline.

     -   At these sales levels, earnings per share would be expected to be in
         the $0.18 to $0.25 range, reflecting negative operating leverage,
         continued costs related to acquisition integrations and manufacturing
         transitions and a temporary increase in the tax rate to 36-38%.

         "As we look out past the next few quarters, our future still looks
bright," said Hunter. "Our growth strategies are firmly in place and we have a
clear plan to achieve our long-term operating margin target of 15%. Barring a
more protracted slowdown than we currently see, we still believe that earnings
of $2.00 per share is within reach for 2007."

the company's ongoing operating performance than GAAP operating income since it
excludes charges that are related to closure of legacy operations.
