Raychem Slow Blow Fuses

Raychem Circuit Protection Slow Blow Surface-mount Fuses feature industry standard 0603 and 1206 chip sizes, high reliability and strong arc suppression characteristics. The fuse’s monolithic, multilayer design helps provide some of the highest current ratings available in the 1206 footprint and enhances high temperature performance in a wide range of circuit protection designs. Designed for DC power applications of up to 63V_DC such as protection of power supplies, capacitor filter banks, LCD backlight inverters, electric motors and portable electronics.
