Description

General part information

0438.500 Series

This 100% Lead Free and RoHS compliant fuse series has been designed specifically to provide over current protection to circuits that see high working ambient temperatures (up to 150ºC). The general design ensures excellent temperature stability and performance reliability. In addition to this, the high i²t values typical of the Littelfuse Ceramic fuse family ensure high inrush current withstand capability.
