Bel Fuse Inc., has announced surface mount and radial leaded Polymeric Positive Temperature Coefficient (PPTC) resettable fuses. The resettable fuses help protect against overcurrent surges and overtemperature faults by limiting the flow of dangerously high current during fault conditions. The PTC devices do not require replacement after a fault event as they reset themselves, allowing the circuit to resume normal operating conditions once the power is removed.
