1812 Recoverable fuse 30V 500mA

Recoverable fuse is made through special processing of Polymer resin (Polymer) and distribution in the conductive particles (Carbon Black).Polymer resin under normal operation will closely bound in crystal structure, the conductive particles of the conductive electrical pathway, the recoverable fuse for low resistance state (a), recoverable fuse line on the current the heat energy produced is small, will not change the crystal structure.When line short circuit or overload, recoverable fuse of large current flows through the heat generated by the melted polymer resin, rapid growth in volume, form a high impedance state (b), working current rapidly decreases, and thus to restriction and protection circuit
