Available in industry standard 1206 and 0603 chip sizes, Littelfuse’s slow-blow chip fuses help provide overcurrent protection on systems that experience large and frequent current surges as part of their normal operation (at voltages up to 63 VDC).

The slow-blow chip fuse’s monolithic, multilayer design helps provide some of the highest current ratings available in the 1206 and 0603 footprints and enhances high-temperature performance in a wide range of circuit protection designs. The devices’ small size, high reliability and strong arc suppression characteristics make them suitable for overcurrent protection of power supplies, capacitor filter banks, Liquid Crystal Display (LCD) backlight inverters, electric motors and portable electronics.
