LittleFuse Inc. (LFUS) upped its second-quarter guidance, citing increasing demand for electronic equipment.

The news sent shares of the circuit protection products manufacturer surging more than 5% in Friday afternoon trading.

But the positive news was offset by the company's announcement that third-quarter sales could drop by $2 million to $3 million due to lost production from a fire at its Taiwan plant.

"Production has resumed, but we will be operating this facility below full capacity for a few months," Chief Executive Gordon Hunter said in a statement.

The company said electronics demand continues to exceed expectations.

For the quarter, the company now expects to earn 78 cents to 88 cents a share, up from its prior view of 69 cents to 77 cents a share.

The company forecasts revenue of $155 million to $160 million up from $148 million to $153 million.
