A thermistor (thermally sensitive resistor) is an electronic device which utilizes the change of resistance when the temperature changes, and is widely used as a temperature sensor and a compensator for an electronic circuit. Thermistors exhibit large changes in electrical resistance with corresponding changes in temperature. The sensitivity to temperature change can result in a thermistor resistance change of 10 million to one over an operating temperature range. Chip thermistors include both positive resistance-temperature coefficient (PTC) thermistors and negative resistance-temperature coefficient (NTC) thermistors. PTC thermistors have been used as an overcurrent protection element. When an electric circuit gets overloaded, conductive polymers of a PTC thermistor emit heat and thermally expand to become high resistance, thereby reducing the current in the circuit to a safe small current level. NTC (negative temperature coefficient) thermistors are widely being used for the purposes of temperature detection and temperature compensation. Because of their sensitivity, accuracy, and stability, thermistors are used extensively for commercial consumer electronic products, automotive, industrial, and medical electronic applications, food handling and processing, communication and instrumentation, computers, military and aerospace, and research and development. Thermistors may find used in photography, blood analysis, myocardial needle probes, thermometers, intravenous catheters, liquid level measurement, automotive climate control, fuel level/temperature, temperature sensors for household appliances such as air conditioners, coffee makers, and data logger applications such as air, soil, liquid temperature probes, portable phones, carphones, quartz oscillators and transceivers.
