The ERTJ series NTC Thermistor is a negative temperature coefficient resistor that significantly reduces its resistance value as the heat/ambient temperature rises. Thermistor is sintered in high-temperature (1200 to 1500°C) and manufactured in various shapes. It"s comprised of 2 to 4 kinds of metal oxides - iron, nickel, cobalt, manganese and copper.
Temperature coefficient of resistance is negative and it"s extremely large
Various shapes, especially compact size components are available
Selection of resistance vale is comparatively free
