      LITTELFUSE ANNOUNCES SONG LONG ACQUISITION AND IRELAND PLANT SHUTDOWN

DES PLAINES, ILLINOIS, JUNE 21, 2006.....Littelfuse, Inc. (Nasdaq/NMS/LFUS)
today announced it has signed a definitive agreement to acquire the assets of
Song Long Electronics Co., Ltd., headquartered in Taiwan, for $5.5 million in
cash. Song Long manufactures metal oxide varistors at its facility in Dongguan,
China. The company has annual sales of approximately $5.5 million, including $2
million of sales to Littelfuse.

"This is an important strategic move for Littelfuse," said Gordon Hunter, Chief
Executive Officer. "Littelfuse's broad, high-quality varistor product offering
is currently hampered by a cost position in Ireland that is not competitive with
today's global market. The Song Long acquisition provides a high-quality,
low-cost China manufacturing platform to which we will transfer this product
line over the next two years."

"Song Long has been a supplier partner to Littelfuse for the past five years.
Over that period, we have developed a strong working relationship with Song
Long's talented management team and have been impressed with their skilled
workforce. Their dedication to quality and customer service will be valuable
assets for Littelfuse," added Hunter.

The downsizing and ultimate closure of the Ireland facility will result in
pre-tax restructuring charges of approximately Euros 14.3 million or about $18
million at today's exchange rate. The cash outflows for this restructuring will
occur largely in 2007 and 2008, but in accordance with accounting guidelines,
the entire charge of approximately $0.53 per share will be booked in the second
quarter of 2006. Cost savings related to the move of the varistor line are
expected to begin in 2007 and reach an annual run rate of at least $10 million
by the end of 2008.

"This acquisition is another step forward in our strategy to expand our
operations in Asia in order to be closer to current and potential customers,
ensure a competitive cost position and participate in the growth of the entire
region," said Hunter.

"The decision to move production from Ireland was difficult, especially because
of the many employees at this facility who have contributed to our successful
growth. However, we believe this step is in the best interest of our company,
our customers and our shareholders over the long term," added Hunter.
