                    LITTELFUSE REPORTS FIRST QUARTER RESULTS

      DES PLAINES, ILLINOIS, APRIL 30, 2008 - Littelfuse, Inc. (NASDAQ/NGS:LFUS)
today reported sales and earnings for the first quarter of 2008.

First Quarter Highlights

   -    Sales for the first quarter of 2008 were $133.7 million, an increase
        of $1.9 million or 1% compared to the first quarter of 2007.
        Automotive and electrical sales increased 8% and 5%, respectively,
        compared to the prior-year quarter, while electronics sales
        declined 1%.

   -    Diluted earnings per share for the first quarter of 2008 were $0.19
        compared to diluted earnings per share of $0.28 for the first quarter
        of 2007.

   -    Adjusted diluted earnings per share (see Supplemental Information)
        were $0.36, which excludes $5.2 million of charges primarily related
        to severance for the recently-announced Matamoros, Mexico plant
        closure. This corresponds with the company's previous guidance of $0.32
        to $0.37 per share.

   -    Capital expenditures for the first quarter of 2008 increased to $11.5
        million compared to $5.1 million in the prior-year quarter due to
        spending for facilities and equipment to support the previously
        disclosed manufacturing transfers. Cash flow from operating activities
        was negative $1.0 million for the first quarter of 2008 compared to $1.0
        million in the prior-year quarter. Increases in inventories to support
        the manufacturing transfers and severance payments related to plant
        closures contributed to the negative cash result.

   -    The company completed the acquisition of Shock Block Corporation in
        the first quarter of 2008. Shock Block supplies high-current ground
        fault protection devices for use in a wide variety of industrial
        applications. Shock Block sales are approximately $2 million annually.

   -    The company repurchased 218,000 shares of its common stock in the
        first quarter at an average price per share of $30.38. At the end of
        the first quarter of 2008, the company had 282,000 shares remaining on
        the authorized stock repurchase plan.

   -    The book-to-bill ratio for electronics for the first quarter of 2008
        was 1.11, which is up from 0.96 at the end of 2007.

      "The first quarter played out largely as we expected, which puts us on
track to meet our plan for the year," said Gordon Hunter, Chief Executive
Officer. "We made excellent progress on our manufacturing transfers. The
automotive business continues to perform well despite headwinds in the North
American market. Electrical sales have slowed from the double digit increases of
last year, but this business continues to grow and generate superior margins.
The electronics business had a slow start to the year, but since the Lunar New
Year in early February, orders have been strong and sales have been increasing."


Second Quarter Outlook

   -    Sales for the second quarter of 2008 are expected to be in the range
        of $142 to $147 million, which represents 10 to 14% growth over the
        prior-year quarter.

   -    As previously stated, margins will be impacted throughout 2008 by
        costs related to manufacturing transfers, including redundant
        overhead, equipment move costs, training and retention incentives.
        These costs are expected to average about $3 million per quarter
        through the remainder of 2008.

   -    Diluted earnings for the second quarter of 2008 are expected to be in
        the range of $0.42 to $0.48 per share.
