PTC Thermistors

TDK PTC Thermistors are thermally sensitive semiconductor resistors made of ceramic components whose electrical resistance rapidly increases when a certain temperature is exceeded. This feature makes TDK PTC Thermistors ideal for use in electrical and electronic engineering applications, for example as resettable fuses against current overload or as short circuit protection in motors. Applications include measurement and control engineering, entertainment, household, and automotive electronics, and data systems and telecommunications.
