TD and Chip Resettable PTCs

Littelfuse’s TD (terminal devices) and Chip Polyswitch devices are designed for use in small and medium automotive motor applications such as power windows, door lock motors and lumbar pump motors. These devices help eliminate problems caused by abnormal function or misuse, such as a motor stall or short circuit.

The TD and chip devices are normally custom made to fit in to motor housing. By mounting them close to the motor windings, they will trip more quickly when the motor windings are hot and more slowly when they are cold.
