PTC NTC Thermistors Comparison
Thermistor, abbreviated for THERMally sensitive resiSTOR.
PTC, abbreviated for Positive Temperature Coefficient.
NTC, abbreviated for Negative Temperature Coefficient.
PTC thermistor resistance increases with temperature rising.
NTC thermistor resistance decreases with temperature rising.
PTC Thermistor are made of doped polycrystalline ceramic on the basis of barium titanate, major material BaTio3.
NTC thermistor are made of polycrystalline mixed oxide ceramics, major material is Mn, Ni, Cu.
PTC thermistors are mainly applied in overcurrent overload and short circuit protection , telecom protection, temperature sensing, temperature protection, motor sensing protection,motor starting, lighting soft switching time delay, self-regulation constant heating, etc.
