Motor thermal protection PTC thermistor

Polymer PTC temperature sensor. A surface mount polymer PTC (positive temperature coefficient) temperature sensor using a conductive polymer polymer composite material as a main material. Different from the traditional ceramic PTC temperature sensor, it adopts an easy-to-install surface-mount form for easy installation;
