Littelfuse 4A F Ceramic Cartridge Fuse, 5 x 20mm

Typical Applications include short-circuit protection of semiconductors such as thyristors, diodes and triacs. Note that with values of greater than 6.3A the use of open type fuseholders is recommended, to reduce the risk of nuisance tripping at or near full rated current.

Very high breaking capacity
Good mechanical/vibration characteristics
Ceramic cartridge bodies are sand filled
