**RETAINER THERMISTOR** RETAINER THERMISTOR NCO-74328-DAIKIN-MCQUAY Thermistors are temperature-sensing resistors whose prime function is to exhibit a large change in resistance with a small change in temperature. They are widely used as inrush current limiters, temperature sensors, self-resetting thermal fuses, and self-regulating heating elements. NTC thermistors are typically made of metal oxides, while PTC thermistors are typically made of conductive polymers. The temperature dependence of the resistance of a thermistor is given by the Steinhart-Hart equation: R(T) = R0 * exp(B * (1/T-1/T0)) where: - R(T) is the resistance of the thermistor at temperature T - R0 is the resistance of the thermistor at a reference temperature T0 - B is a material-specific constant The value of B is typically negative for NTC thermistors and positive for PTC thermistors.
