<font> Littelfuse, Inc. ( LFUS ) today announced revised guidance for the second quarter of 2009 as follows: </font>

<font> -- Sales for the second quarter of 2009 are now expected to be approximately $101 million, which represents a 20% sequential increase compared to the first quarter of 2009. Previous guidance called for a 10-15% sequential increase. </font>

<font> -- On a GAAP basis, the company expects to report a loss of ($0.12) to ($0.14) per diluted share, which includes restructuring charges of approximately $7 million (pre-tax) or $0.22 per diluted share. These restructuring charges relate to plans announced on May 19, 2009 to further consolidate manufacturing sites and further reduce operating expenses. </font>

<font> "Automotive and electronics sales improved more than expected in the second quarter, and electrical sales increased in line with normal seasonality," said Gordon Hunter, Chief Executive Officer. "With the cost reductions that have been implemented, the current sales run-rate is well above our breakeven point, excluding restructuring charges. While most end markets are still weak, channel inventories have declined considerably and we are now into the traditionally stronger part of the year." </font>

<font> No conference call will be held in conjunction with this guidance revision. Littelfuse is scheduled to release financial results for the second quarter on Wednesday, July 29, 2009. </font>
