Description
General part information
0437003 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 150°C). 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.
