Low-Resistance SMT PTC Resettable Fuses – PTSLR Series
Eaton's surface-mount PTC resettable fuses provide overcurrent and overtemperature protection
Eaton Bussmann® series PTSLR surface-mount fuses offer a high resistance during fault conditions to prevent current from flowing in the circuit until the cause of the fault is removed and the device cools. Unlike one-time fuses, PTSLR fuses do not need to be replaced immediately after a trip, which provides the overcurrent and overtemperature protection needed in applications like rechargeable battery packs, USB ports, and small DC motors.
