SURFACE-MOUNT FUSES High-Current-Rated Chip Fuses The monolithic multilayer design of the Littelfuse high-currentrated chip fuses helps to provide some of the highest current ratings available in the 1206 size 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, servers, communications equipment, voltage regulator modules, and other high current, small size applications. BENEFITS APPLICATIONS * Glass ceramic monolithic structure provides stability in application cycling * Communications equipment * High-current rating in a small package allows more efficient use in system space * Power supplies * Strong arc suppression in overcurrent conditions * Voltage regulator modules * Servers FEATURES * Lead-free materials and RoHS compliant * Halogen free (refers to: Br900ppm, Cl900ppm, Br+Cl1500ppm) * Monolithic multilayer design * High-temperature performance * -55C to +150C operating temperature range RoHS Compliant, ELV Compliant HF Halogen Free Specifications subject to change without notice.
