NANO Fuses

Littelfuse NANO® Fuses are fast-acting, high-performance fuses available in a wide range of available current ratings. The portfolio includes 448 NANO2® SMF Fuses, which are fast-acting fuses available in current ratings from 62mA to 15A. The 443 NANO2 series features square surface-mount, time-lag devices with a 250VAC voltage rating. Littelfuse 449 NANO2 Slo-Blo® Fuses offer enhanced inrush withstand characteristics over NANO2 Fast-Acting Fuses. The 456 series is designed to support higher current requirements and is fully compatible with lead-free solder alloys. Littelfuse 456 fuses are ideal for storage system powers, cooling fan systems for PC servers, and base station power supplies. Littelfuse NANO Fuses include additional series as well.
