NTC stands for Negative Temperature Coefficient, which refers to semiconductor materials or components with a high 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 using ceramic technology. These metal oxide materials all have semiconductor properties because they are completely similar in conductivity to semiconductor materials such as germanium and silicon.
When the temperature is low, these oxide materials have fewer charge carriers (electrons and holes), so their resistance values are higher; As the temperature increases, the number of charge carriers increases, so the resistance value decreases.
The range of variation of NTC thermistors at room temperature is 100-1000000 ohms, with a temperature coefficient of -2% to 6.5%.
NTC thermistors can be widely used in temperature measurement, temperature compensation, surge current suppression, and other applications.
