Development history of NTC thermistor

NTC（Negative Temperature Coefficient）is a kind of thermistors. With the increase of temperature, the resistance of NTC thermistor will decrease exponentially. The following photo is a kind of NTC thermistors.

The development of NTC thermistor has a long history. In 1834, the characteristic of negative temperature coefficient of silver sulfide was discovered for the first time. In 1930, scientists found that Cu2O-CuO also has a negative temperature coefficient of performance, and successfully applied it in temperature compensating circuits of aviation instruments. And then, with the development of transistor technology, significant progress in the study of thermistor has been obtained. In 1960, the NTC thermistor was developed. It has been widely used for measuring temperature, controlling temperature, temperature compensation and so on. 

There are many kinds of NTC thermistors with high quality, high stability and long service lifetime in our company (ATI). These thermistors can be used for temperature control of TEC controller.
