ITEM 2.               ACQUISITION OR DISPOSITION OF ASSETS

           On July 7, 2003, the Registrant acquired all the issued and
outstanding shares of the capital stock of Teccor Electronics, Inc., a Texas
corporation ("Teccor"), from Ranco Incorporated of Delaware, a Delaware
corporation ("Ranco") and a subsidiary of Invensys plc, a UK corporation. At
closing, Littelfuse paid Ranco $44 million, which amount is subject to a
post-closing adjustment based on a determination of the amount of certain assets
and liabilities of Teccor on June 28, 2003. Additionally, if the net sales of
certain products (primarily those currently manufactured by Teccor) during
calendar year 2005 equal or exceed $107 million, then the Registrant shall pay
to Ranco on January 31, 2006, $5 million as additional purchase price. The
purchase price was arrived at pursuant to negotiations between the Registrant
and Ranco and reflects the Registrant's estimate of the fair market value of the
Teccor shares. The Registrant borrowed the cash portion of the purchase price
under its Second Amended and Restated Credit Agreement with Banc One, Bank of
America National Trust and Savings Association, National City and The Northern
Trust Company. The press release, dated July 8, 2003, announcing the Teccor
acquisition is included as an exhibit to this Form 8-K and is incorporated
herein by reference.
