Thermistor Derating Curve
Resistor Thermistor ratings are normally specified at +25oC and must be reduced as the thermistor temperature increases. A derating chart is often used, with derating starting at 25oC [see above]. Since parameters are application dependent, power de-rating curves or charts should be considered general rather than absolute, and only used as a guideline. The safest designs use the largest physical size operating at conservative temperatures and power ratings.
