Compact Fuse Allows Faster, Safer, Higher-Wattage Product Charging
Littelfuse Inc.

The compact 777 Series fuse provides protection for higher-wattage, wall-mount chargers for battery-powered electronic equipment. The axial lead, 3.6 mm x 9 mm fuse employs a unique filler material that provides a finely tuned balance between the surge tolerance necessary to prevent nuisance fuse tripping with the fuse’s ability to open safely when a short-circuit occurs. It can withstand up to 24 hits of 7.5-kV ring-wave surge and will open safely on a direct short condition without producing soot, sparks, and sounds. Typical applications include wall-mount smartphone and tablet chargers and 10W to 20W power supply modules. A datasheet is available at
