463 Series - NANO²® Very Fast-Acting Subminiature Surface Mount Fuse
Brand: Littelfuse, IncThe 463 Series NANO²® fuse is a fast-acting, very high current fuse designed for high operating current applications. It offers enhanced thermal cycling endurance (up to 500 cycles).
Its low temperature rise and excellent temperature stability characteristics make it ideal for use in datacom and telecom equipment like high-end servers, base stations, power supplies, and blade computing applications.
The 463 Series offers high-amp circuit protection, ultra-high interrupting ratings (up to 500A@72VDC), and a compact (10.1mm x 3.12mm x 3.12mm) surface-mount form factor to save board space.
