R25 : Rated zero-power resistance value at 25ЊC.
B value : determined by rated zero-power resistance at 25ЊC and 85ЊC.
Residual resistance is the maximum value when maximum rating current is applied.
Time when thermistor temperature reaches 63.2% of the temperature difference. The value is measured in the air.
