PTC Thermistors

PTC is a positive temperature coefficient thermistor. It is a typical semiconductor resistance with temperature sensitivity. When the temperature exceeds a certain temperature (Curie temperature), its resistance value increases with the increase of temperature.

Product introduction

Product Introduction
PTC is a positive temperature coefficient thermistor. It is a typical semiconductor resistance with temperature sensitivity. When the temperature exceeds a certain temperature (Curie temperature), its resistance value increases with the increase of temperature.
