Description

General part information

0408003.WR Series

Littelfuse 408 Series is a 100% lead-free, RoHS compliant, and halogen-free fuse designed specifically to provide overcurrent protection to circuits that operate under high working ambient temperatures up to 150°C and high in-rush currents. The general design ensures excellent temperature stability and performance reliability. This high I2t time lag fuse is designed to have ultra-high in-rush current withstand capability to avoid nuisance fuse open.
