Thermistor

 

Catalogue:thermistor

A thermistor is a thermal resistor – a resistor that changes its resistance with
temperature. Technically, all resistors are thermistors – their resistance changes
slightly with temperature – but the change is usually very very small and difficult to
measure. Thermistors are made so that the resistance changes drastically with
temperature so that it can be 100 ohms or more of change per degree!
