简介: Introduction: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 , self-resetting overcurrent protectors, and self-regulating heating elements. NTC thermistors are designed to be most sensitive to temperature changes in the lower (colder) end of the range. They are most commonly used to sense temperature. PT
