NTC thermistor is a negative temperature coefficient thermistor made of polycrystalline mixed oxide ceramics, and its resistance decreases with increasing temperature.
The resistance change of the NTC thermistor can be realized externally through changes in the ambient temperature, or internally through self-heating generated by the current flowing through the device.
NTC thermistor is used for surge current limitation, surge suppression, temperature measurement induction compensation, etc. Due to its low resistance under working conditions, the power consumption of Power NTC thermistors is much lower than the fixed resistances often used in inrush current limiters.
