456 Series fuse offers high-amp circuit protection in a tiny package compatible with faster pick and place electronics assembly processes

Addressing customer requests for smaller embedded device protection of higher-current applications, Littelfuse has launched a new series of fast-acting ROHS and UL compliant 20A and 30A subminiature surface-mount fuses.

The 456 Series was designed for situations where an ultra-small profile and higher-amp, pick and place surface mount fuse is desired.

Measuring only 10.10-mm (0.397-in.) long and 3.12-mm (0.123 in.) width and height, Littelfuse Nano2® 456 Series ceramic fuses are available in 30A and 20A ratings, with interrupting ratings are 300A at 65 VAC and 100A at 125 VAC respectively.

The 456 Series enables circuit engineers to design-in reliable primary and secondary over-current protection with a single miniature fuse. The 456 Series can serve as a more stable and reliable alternative to using similar smaller-amp Nano fuses in tandem. Prior to the introduction of the 456 Series, a dual-fuse method was the only way to achieve circuit protection greater than 15A using Nano fuses.

This product is now being offered globally. The 456 Series is also targeted to protect applications such as wireless base stations, power supplies, large scale storage systems and other higher current electronic systems.
