The thermistor is a type of sensitive component and is divided into a positive temperature coefficient thermistor (PTC) and a negative temperature coefficient thermistor (NTC) according to the temperature coefficient. Typical characteristics of thermistors are temperature sensitive and exhibit different resistance values at different temperatures. The positive temperature coefficient thermistor (PTC) has a higher resistance value at higher temperatures, and the lower the resistance value of the negative temperature coefficient thermistor (NTC) at higher temperatures, they belong to the semiconductor device.

Product hotspots:

1. The sensitivity is higher, and the temperature coefficient of resistance is 10~100 times larger than that of metal, and the temperature change of 10-6 °C can be detected;

2, small size, able to measure the temperature of the voids, cavities and blood vessels in the body that other thermometers cannot measure;

3, easy to use, the resistance value can be arbitrarily selected between 0.1 ~ 100kΩ;

4, easy to process into complex shapes, can be mass-produced;

5. Good stability and strong overload capability.
