Littelfuse 408 Series Surface Mount Fuses

Littelfuse 408 Series Surface Mount Fuses are 100% lead-free, RoHS compliant, and halogen-free fuses explicitly designed 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 temperature stability and performance reliability. Littelfuse 408 Series Surface Mount Fuses have a high I2t time lag and are designed to have an ultra-high in-rush current withstand capability to avoid nuisance fuse openings.
