Insurance of resistance
insurance resistors fusing resistors, insurance both resistors and fuses the two resistors function normally can be used as resistors, once the current exception when it played its role in fuse to protect the equipment.
insurance resistors in the circuit plays a dual role of fuses and resistors, are mainly used in power supplies output circuits. Insurance of resistance values are usually small (a few ohms to dozens of ohm), less power ( 1/8---1W).
circuit load fault, when there is a flow, insurance of resistance temperature in a short period of time will increase to 500 deg-600 c, resistance heated peeling of layer fuses, play the role of fuse, achieve the aim of enhancing the overall security.BACK
