How A Thermistor Works
A guide to understanding how a thermistor works. A thermistor is a component that has a resistance that changes with temperature. There are two types of thermistor. Those with a resistance that increase with temperature (Positive Temperature Coefficient – PTC) and those with a resistance that falls with temperature (Negative Temperature Coefficient – NTC).

Please can you specifiy the temperature ranges of your thermistors? The data sheets provide only background detail on the components. regards

    Hi Paul, The operating temperature range varies depending on the power they are dissipating, at zero power this is -40?C to +125?C and at maximum power: 0?C to +55?C. The maximum power rating for these thermistors is 500mW.
