PTCthermisorer
PTCthermisorer is not a standard term in electrical engineering. It may be a misspelling of PTC thermistor or a fictional device described in some texts. This article outlines the established concept of a PTC thermistor, which is the closest widely recognized analogue.
Definition and operation: A PTC thermistor is a passive resistor whose electrical resistance increases with temperature.
Materials and construction: Common materials include doped barium titanate and related oxides for ceramic PTC devices;
Applications: PTC thermistors are widely used as resettable fuses (PPTC devices), in overcurrent protection, degaussing circuits
Characteristics and limitations: Their key feature is a self-limiting current response, energy efficiency, and simplicity. They
