3.Terms and General Characteristics




Zero Power Resistance


At 25°C, the measured resistance value can be neglected compared to the general tolerance when the change of the resistance is made  through its self-heat of the resistor.


See Electrical Parameters


    T1*T2         R1

B=          * ln (        )  

    T2   T1       R2

The B value can be calculated using the zero power resistance value at 25°C and 50°C. The equation is as above.

See Electrical Parameters


Thermal Dissipation Constant

The ratio of the change of the dissipation power to the corresponding change of the temperature at specified temperature. The unit is: mw/°C

See Electrical Parameters





Under zero power condition, thermal time constant is the time required by a thermistor that its body temperature reach 63.2% of the difference between its initial and final temperature.

See Electrical Parameters

Operating Temperature

Allowable temperature range while the thermistor work continuously for long time



Damp Heat

The sample should be subjected to 40±2°C, relative humidity 93±3% for 48±2 hours, then stored at room temperature and humidity

for 1 hour.

No visible damage,themark is clear ,no

No visible damage,themark is clear,nobreakdown or arcing.Insulating resistance is>100MΩ. The change ratio of the resistance is within ±15%.

Withstand Voltage

Applied AC voltage of 700v between the lead of the resistor and the insulating coating for 1 minute

No breakdown

or arcing


Resistance to Soldering Heat
