240V 470V NTC SMD Thermistor , SMD NTC Temperature Sensor
NTC SMD Thermistor 240V 470V Thermistor NTC Temperature Sensor for SMD Tempe
Thermistors are a kind of sensitive elements, which can be divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to different temperature coefficients. The typical characteristic of thermistors is that they are sensitive to temperature and show different resistance values at different temperatures. Positive temperature coefficient thermistors (PTC) have higher resistance values at higher temperatures, while negative temperature coefficient thermistors (NTC) have lower resistance values at higher temperatures. They both belong to semiconductor devices.
