SURFACE-MOUNT FUSES
High-Current-Rated Chip Fuses
The monolithic multilayer design of the Littelfuse high-current-
rated 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
• Voltage regulator modules
• Power supplies
• High-current rating in a small package allows more
efficient use in system space
• Servers
• Strong arc suppression in overcurrent conditions
FEATURES
• Lead-free materials and RoHS compliant
• Halogen free
(refers to: Br900ppm, Cl900ppm, Br+Cl1500ppm)
• Monolithic multilayer design
• High-temperature performance
• -55°C to +150°C operating temperature range
