Littelfuse Raises Guidance for Second Quarter

CHICAGO, June 11, 2010 – Littelfuse, Inc. (NASDAQ:LFUS) today announced revised guidance for the second quarter of 2010 as follows:

• Sales for the second quarter of 2010 are now expected to be in the range of $155 to $160 million, which represents sequential growth of 7% to 11%. Previous guidance called for sales in the range of $148 to $153 million.
• Earnings for the second quarter of 2010 are expected to be in the range of $0.78 to $0.88 per diluted share. Previous guidance called for earnings in the range of $0.69 to $0.77 per diluted share.

“Electronics demand continues to exceed our forecast in all end markets and all geographies,” said Gordon Hunter, Chief Executive Officer. “Startco is performing at the high end of expectations and the electrical fuse business is steadily improving.”

“Overall, our operations teams have done a very good job ramping up production to meet increasing customer demand,” said Phil Franklin, Chief Financial Officer. “Recently, however, we have had a supply interruption at our semiconductor factory in Taiwan. Equipment failure caused a fire in a limited area that was quickly brought under control. Production has resumed, but we will be operating this facility below full capacity for a few months. This is expected to constrain sales by $2 to $3 million in the third quarter.”

“Orders and backlog remain robust in all geographies, which leads us to believe we will see typical seasonal strength in the third quarter,” said Hunter. “The final manufacturing transfers are on track and are expected to deliver additional savings beginning in the third quarter.”

No conference call will be held in conjunction with this revised guidance. Littelfuse is scheduled to release financial results for the second quarter on August 5, 2010.
