THERMISTOR

“Thermistor” is the generic name given to thermally sensitive resistors. Negative temperature

coefficient thermistor is generally called as thermistor. Thermistor is a semi conducting ceramic

resistor produced by sintering the materials at high temperature and made mainly from metal

oxide. Depending on the manufacturing method and the structure, there are many shapes and

characteristics for various purposes such as temperature measurement, temperature

compensation etc.

Temp2 [°C] @ Rst2 [KΩ] 2 ~ 40

Temp2 = 95.512 - 23.47 * ln (Rst)

Temp1 [°C] @ Rst2 [KΩ] 0 ~ 70

Temp1 = 110.139 - 28.929 * ln (Rst)

Rst2 [KΩ] @ Temp [°C] 10~80

Rst2 = 58.189

(-0.042Temp)

Rst1 [KΩ] @ Temp [°C] 0~180

Rst1 = 48.881

(-0.037Temp)

Rst - Thermistor resistant as function at temperature

Temp- Electric motor temperature
