Design-in Over-current Protection with a Single Miniature Fuse

Wed, 10/10/2007 - 8:43am
Addressing the need for smaller embedded device protection of higher-current applications, Littelfuse announces the release of a new series of fast-acting ROHS and UL compliant, subminiature surface-mount fuses. Measuring 10.10 mm (0.397 inches) long and 3.12 mm (0.123 inches) width and height, the Nano2 456 Series ceramic fuses are available in 20 and 30 A with interrupting ratings of 100 A at 125 VAC and 300 A at 65 VAC respectively. The 456 Series was designed for situations where an ultra-small profile and higher-amp, pick and place surface mount fuse is desired. In addition to serving as an embedded secondary protection solution for PC servers, the 456 Series is also targeted to protect applications such as power supplies, wireless base stations, large scale storage systems and other higher current electronic systems. The 456 Series enables circuit engineers to design-in reliable primary and secondary over-current protection with a single miniature fuse. Beyond the benefit of space-saving design, the 456 Series can serve as a more stable and reliable alternative to using similar smaller-amp Nano fuses in tandem.
