Resistance temperature characteristic
Resistance temperature characteristic is often referred to as the resistance temperature characteristic, which refers to the relationship between the zero power resistance of the thermistor and the temperature of the resistance body under the specified voltage. The temperature coefficient of Tmax and Tmin (T=Tmax-Tmin) is the important parameter to characterize the resistance temperature characteristic. The smaller the T, the better the PTC characteristics, the high resistance ratio and large temperature coefficient of PTC components, the automatic constant temperature effect of the heat source is good, and the pressure characteristic is good. According to this characteristic, it can be used in sensor, temperature compensation, over current protection.
