PTC Thermistors

PTC thermistors are very extensive in the application. They are often used as self-regulating protective component, for example in engines. In some cases, they are also suitable for temperature measurement or as a heating element.

Most PTC thermistors work in most cases, similar to a thermal switch, from a certain temperature (Curie temperature) occurs an abrupt change in resistance. Based on this, a current can be limited or temperature are determined.
