An NTC thermistor is a thermally sensitive resistor whose resistance exhibits a large, precise and predictable decrease as the core temperature of the resistor increases over the operating temperature range. ... Where k is the negative temperature coefficient, ΔT is the temperature difference, and ΔR is the resistance change resulting from ...

A thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors.The word is a portmanteau of thermal and resistor.Thermistors are widely used as inrush current limiters, temperature sensors (negative temperature coefficient or NTC type typically), self-resetting overcurrent protectors, and self-regulating heating elements (positive ...
