This range of miniature ceramic cartridge fuses are either ultra-rapid fuses (FF) or fast acting fuses (F) The ultra-rapid fuses operate at higher temperatures so are ideal to provide circuit protection to semiconductor devices. The fast-acting fuses are ideal to protect less sensitive components. Fast acting fuses are the most popular fuse. 6.3 x 32mm
More Information:
Why choose a glass fuse?
Glass and ceramic fuses have similar properties. However you may choose a glass fuse as it enables you to see the inside of the fuse. Therefore it is easier to determine whether the fuse has blown.
What size is it?
6.3 x 32mm is a miniature cartridge size. Miniature fuses are ideal for the protection of electrical appliances, electronic equipment and component parts
What Speed is it?
These particular fuses are either (FF) ultra-rapid or (F) fast acting speed rated which means it is a fast acting fuse, FF fuses are good for semiconductor devices like thyristors, diodes and transistors.
What is Breaking Capacity?
Breaking capacity is the level of current that the fuse can safely handle without exploding or rupturing. The breaking capacity of your fuse should be greater than the fault current of your electronic circuit. This particular fuse is HBC (High Breaking Capacity).
