Littelfuse Non-Resettable Fuse 20A, 125V ac, Ceramic Body, Fast Acting, 456 Series 0456020.ER

Littelfuse 0456020.ER Non-Resettable Fuse is a high-quality 20A fast acting fuse designed for protection of low voltage circuits requiring reliable, compact fusing solutions. Featuring a robust ceramic body, this fuse withstands elevated temperatures and harsh operating conditions ranging from -55°C to 125°C.

This fuse is part of the Littelfuse 456 Series NANO2 surface mount fuse family, specifically developed to support high current applications in compact footprints, perfectly suited for modern electronic assemblies and surface mount technology (SMT) manufacturing.

The fuse body measures 3.12mm in width and height, with 10.08mm depth, making it suitable for space-constrained designs. Silver plated brass terminals ensure excellent electrical performance and resistance to corrosion over extended use.

With a breaking capacity of 50A, this device safely interrupts fault conditions, protecting valuable semiconductor components and equipment. The fast acting fuse characteristic (FF) makes it ideal for protection of sensitive ICs found in computer motherboards, power supplies, audio/visual devices, portable telecommunications equipment, medical instruments, and alarm systems.

Compliance with CSA and UL 248-14 standards, along with RoHS certification, assures high product quality and environmental compliance. The fuse is delivered in reel packaging to facilitate automated assembly and high volume production.
