PTC Devices - LITTELFUSE, SCHURTER, BUSSMANN

Product Details

PTC (Positive Temperature Coefficient) device commonly known as
a resettable fuse, polyfuse or polyswitch is used to protect against overcurrent faults in electronic circuits. Like traditional fuses, these PTC devices limit the flow of dangerously high current during fault conditions and resets after the fault is cleared and power to the circuit is removed, thereby helping to reduce warranty, service and repair costs.
