Thermistors have those terms(3)

5. Negative temperature coefficient thermistor

We call the negative temperature coefficient as the temperature increases and the resistance decrease. The temperature characteristic of the JEC thermistor is a negative temperature coefficient. Therefore, the thermistor is a negative temperature coefficient thermistor

6. B constant

Using the resistance value at 2 points around the ambient temperature, the constant of resistance change is calculated according to the following formula.

B=In (R/R0) / (1/T-1T0)

R: the resistance value at ambient temperature of T (K) R0: the resistance value when the ambient temperature is T0 (K).
