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 limiter, temperature sensors (Negative Temperature Coefficient or NTC type typically), self-resetting overcurrent protectors, and self-regulating heating elements. (Positive Temperature Coefficient or PTC type typically).
Thermistors are of two opposite fundamental types:
With NTC, resistance Decreases with temperature to protect against inrush overcurrent conditions. Installed series in a circuit.
With PTC, resistance Increases with temperature to protect against overvoltage conditions. Installed parallel in a circuit.
