High Voltage Explosion Proof 10.1x3.1mm 4012 Time Delay Surface Mount Fuse 1A 600VAC 350VDC
AOLITTEL NANO² SMD fuse is ideal for use in Datacom and telecom equipment
The Littelfuse 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 500 A at 72 VDC), and a compact (10.1 mm x 3.12 mm x 3.12 mm) surface-mount form factor to save board space.
Features & Benefits
High current rating (15 – 30 A) with higher voltage up to 100 VDC
