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.
Benefits:
•Time-delayed design prevents nuisance openings in pulsed and high inrush
current applications
