Waterproof Stainless Steel Sheath NTC 10K 1% 3950 Thermistor Accuracy Temperature Sensor Cable Probe
Negative temperature coefficient thermistors are made of metal oxides such as manganese, cobalt, nickel and copper, and are manufactured by ceramic technology. These metal oxide materials all have semiconductor properties, because they are completely similar to semiconductor materials such as germanium and silicon in terms of conductivity. When the temperature is low, the number of carriers (electrons and holes) in these oxide materials is small, so its resistance value is high; as the temperature increases, the number of carriers increases, so the resistance value decreases. The range of NTC thermistor at room temperature is 100~1000000 ohms, and the temperature coefficient is -2[%]~-6.5[%].
