JK High Quality PPTC Devices

JKPPTC (Jinke Polymeric Positive Temperature Coefficient) devices, also name as resettable fuse, help protect against harmful overcurrent surges and overtemperature faults.

Like traditional fuses, these devices limit the flow of dangerously high current during fault conditions. The JKPPTC device, however, resets after the fault is cleared and power to the circuit is removed, thereby helping to reduce warranty, service and repair costs.

JKPPTC have passed ISO9001 Quantity Certificate, ISO14001, RoHS, TS16949, REACH, TUV and UL etc, so the product quality can be guaranteed.
