Fuse Datasheet

463 Series

NANO2^®Fuse

RoHS

Description

The 463 series NANO²^®is a fast-acting, very high current fuse

designed for high operating current applications. It offers superior

thermal cycling endurance of 500 cycles with its low temperature

rise and excellent temperature stability characteristics. It is ideal to

be used in datacom and telecom equipment such as 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 small size (10.1 mm

x 3.12 mm x 3.12 mm) and surface-mount form-factor to help

space saving.

Features & Benefits
