Product Description

This 100% lead-free, RoHS compliant and halogen-free 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.
