Nominal Zero-Power Resistance at 25℃ (R25)

Ambient temperature:25±0. 05℃

Measuring electric power:≤0.1mW


Nominal B Constant

Measure the resistance at the ambient temperature of 25±0. 05℃, 50±0. 05℃ or 85±0. 05℃.
B(25-50℃)= lnR25 −lnR50 B(25-85℃)= lnR25 −lnR85

T:Absolute temperature (K)

Thermal Time Constant


The total time for the temperature of the thermistor to change by 63.2% of the difference from ambient temperature T0 (℃) to T1 (℃) by the drastic change of the power applied to thermistor from Non-zero Power to Zero-Power state, normally expressed in second(S).

Dissipation Factor
0201 0402 0603 0805 3435K 3950K SMD NTC Thermistor Surface Mount Thermistor 3
The required power which makes the NTC thermistor body temperature raise 1℃ through self-heated, normally expressed in milliwatts per degree Celsius (mW/℃). It can be calculated by the following formula:
δ= W T−T0

Rated Power

The necessary electric power makes thermistor’s temperature rise 100℃ by self-heating at ambient temperature 25℃.

Permissible operating current

The current that keep body temperature of chip NTC on the PC board in still air rising 1°C by self -heating.
