Description:

Micro fuse is an electric element protecting electric devices. It is commonly connected with a circuit in series, and when fault current increases to a certain value, the fuse blows out to cut off the circuit so as to fulfill an aim of protecting other equipment in the circuit. The fuse is the most commonly used component in a over-current protection circuit. The traditional fuse mainly consists of two parts of a tube body, of which both ends have metal connecting terminals, and metal melt in the tube body. The majority of fuses are cylinder-shaped, namely cartridge construction. But nowadays, with the fast development of advanced technology, some special materials are well applied, the fuse industry has started to move forward in the direction of sub-miniature products and a series of new products such as Surface Mounted Devices type fuse are successively developed.
