Product Description

The 438 Series is a 100% lead-free, RoHS compliant and halogen-free fuse series designed specifically to provide over-current protection to circuits that operate under high working ambient temperature up to 150°C. The general design ensures excellent temperature stability and performance reliability. The high I²t values which is typical in the Littelfuse ceramic fuse family ensure high inrush current withstand capability.
