452/454 Series SMT Fuses

Littelfuse 452/454 Series SMT Fuses are part of the NANO^2®Slo-Blo^® series fuse family, which features enhanced inrush withstand characteristics over existing NANO²Fast-Acting fuses. This "time delay" fuse design accommodates inrush currents that normally cause a fast-acting fuse to open, helping solve the nuisance “opening” problem. The compact 452/454 series provides low-temperature re-rating and contains models in a wide range of current ratings (from 0.375A to 12A). These Slo-Blo fuses can operate between -55°C and 125°C temperatures. Littelfuse 452/454 series fuses are ideal for game consoles, industrial equipment, computer servers, laptops, power supplies, and can serve as the AC line fuse in LED lighting applications.
