NTC, PTC thermistor

NTC is a negative temperature coefficient thermistor thermistor, its resistance decreases with temperature, can be used to stabilize the operating point of the circuit. PTC Thermistors are has a positive temperature coefficient thermistor. Before they reach a specified temperature, resistance decreases as the temperature increases and slow down when the temperature is over, its resistance increases sharply. This particular temperature called the Curie point. Curie point PTC Thermistors change their change in proportion of each component in the material. It is widely used in household appliances such as color TV's degaussing thermostat for resistance, rice cookers and other.
