Thermistor is a kind of sensitive element, which can be divided into positive temperature coefficient thermistor according to different temperature coefficient
Resistor (PTC) and negative temperature coefficient thermistor (NTC). The typical characteristic of thermistor is the temperature
Sensitive, different resistance values at different temperatures. Positive temperature coefficient thermistor (PTC) at
The higher the temperature is, the higher the resistance is, and the lower the negative temperature coefficient thermistor (NTC) is.
They both belong to semiconductor devices.
