NTC stands for Negative Temperature Coefficient (熱敏電阻). Its core characteristic is that its resistance value decreases as the temperature rises. This seemingly simple inverse relationship makes it an ideal tool for temperature measurement.
NTC公司 (負溫度系數) temperature sensor is a temperature measuring element that uses the exponential decrease in the resistance of a thermistor as the temperature rises. Its core is a ceramic semiconductor made by sintering metal oxides (such as manganese, cobalt, and nickel), and the temperature is inferred by measuring the change in resistance. The following are its core technical characteristics, 應用, and selection points:
