Description
In response to new equipment requirements, Littelfuse
LA50QS series fuses were developed to improve the overall
performance of semiconductor fuses. The LA50QS provides
the best protection features including lower I2t, longer life
when subjected to cyclic loading and lower watts loss.
LA50QS is today’s choice for the protection of dynamic solid
state equipment.
