Negative temperature coefficient (NTC) thermistor refers to the thermistor phenomenon and material with a negative temperature coefficient that decreases exponentially with temperature rise. The material is a semiconductor ceramic made by fully mixing, molding, and sintering two or more metal oxides such as manganese, copper, silicon, cobalt, iron, nickel, and zinc. It can be made into a material with a negative temperature coefficient. (NTC) thermistor. Its resistivity and material constants vary with material composition ratio, sintering atmosphere, sintering temperature and structural state. Non-oxide NTC thermistor materials represented by silicon carbide, tin selenide, and tantalum nitride have also appeared.
