ABSTRACT:
A component consisting of two coupled PTC thermistors with the first thermistor having a lower cold resistance than the second thermistor and the first thermistor having a higher resistance at the operating temperature than the second thermistor. According to the invention, the electric connection to the second thermistor is made directly by solely mechanical contacts to the surface of the ceramic thermistor body. This means a considerable simplification during manufacture, as the second thermistor need not be provided with electrode layers.
