What is NTC?
NTC (Negative Temperature Coeff1Cient) refers to the temperature rise with the resistance index is reduced, Thermistor with negative temperature coefficient and material. The material is made of manganese, copper, silicon, cobalt, iron, nickel, zinc and other two or more metal oxides. For the full mixing, molding, sintering and other technology made of semiconductor ceramics, Can be made with a negative temperature coefficient (NTC) thermistor. The resistivity and material constant vary with the material composition ratio, sintering atmosphere, sintering temperature and structure state.
Now also appeared to silicon carbide, tin selenide, tantalum nitride as the representative, Non-oxidant NTC thermistor material.
