What's a thermistor ?

A thermistor is a temperature sensitive resistor. They are often used as a temperature sensor. The term thermistor is a contraction of the words "thermal" and "resistor". All resistors have some dependency on temperature, which is described by their temperature coefficient. In most cases, the temperature coefficient is minimized, but in the case of thermistors a high temperature coefficient is achieved. Unlike most other resistors, thermistors usually have negative temperature coefficients (NTC) which means the resistance decreases as the temperature increases. These types are called NTC thermistors. Thermal resistors with a positive temperature coefficient are called PTC thermistors (Positive Temperature Coefficient).

The working principle of NTC negative temperature coefficient thermistor

NTC is the abbreviation of Negative Temperature Coefficient, which means negative temperature coefficient. It generally refers to semiconductor materials or components with a large negative temperature coefficient. The so-called NTC thermistor is a negative temperature coefficient thermistor. It is mainly made of metal oxides such as manganese, cobalt, nickel and copper, and is made by ceramic technology. These metal oxide materials all have semiconducting properties because they are completely similar to semiconductor materials such as germanium and silicon in electrical conductivity. When the temperature is low, the number of carriers (electrons and holes) of these oxide materials is small, so the resistance value is higher; as the temperature increases, the number of carriers increases, so the resistance value decreases. The variation range of NTC thermistor at room temperature is 100~1000000 ohms, and the temperature coefficient is -2%~-6.5%. NTC thermistors can be widely used in temperature measurement, temperature control, temperature compensation and so on.
