Abstract

A PTC thermistor element for a tempering device may include a main body, which may have a positive temperature coefficient. The main body may have PTC thermistor components, a core, and ceramics components at least in the core. The PTC thermistor components may have a positive temperature coefficient, and the ceramics components may have a thermal conductivity of at least 2.5 W/mK. The ceramics components may be disposed in a distributed manner.
