              LITTELFUSE TO MOVE TECCOR WAFER FABRICATION TO CHINA
              ----------------------------------------------------


         DES PLAINES, ILLINOIS, DECEMBER 6, 2006 -- Littelfuse, Inc.
(NASDAQ/NGS:LFUS) today announced plans to transfer its semiconductor wafer
manufacturing from Irving, Texas to Wuxi, China in a phased transition over the
next three to four years. Upon completion of the transfer, the Irving facility
will be closed.

         Littelfuse will invest approximately $16 million to build a new wafer
fabrication facility in Wuxi adjacent to an existing plant the company acquired
in May 2006 as part of its purchase of Concord Semiconductor. This project is
expected to generate $9 to $10 million of annual savings once the transfer from
Irving is complete. The Irving plant closure will result in pre-tax
restructuring charges of approximately $2.5 million in the fourth quarter of
2006 and approximately $3.5 million over the period of 2007 to 2010.

         "We are committed to making this transition as seamless as possible for
our customers," said Gordon Hunter, Chief Executive Officer of Littelfuse. "As
part of that commitment, we will maintain continuous production capabilities for
all products throughout the move."

         The Irving facility produces thyristor surge protection and power
control devices. Littelfuse acquired the Irving operation in 2003 through its
acquisition of Teccor Electronics Corporation. Approximately 180 employees in
Irving will be affected by the move.

         "This was a difficult decision given that Irving employees have been a
significant part of our growth and success," said Hunter. "However, we believe
this move is in the best interest of our company, our customers and our
shareholders over the long term."
