The maximum value of power, and rated power is same under the condition of ambient temperature 25 C or less. If the temperature exceeds 25 C, rated power depends on the decreased power dissipation curve. Please see Operating Power for details. 2 Dissipation factor : The constant amount power required to raise the temperature of the Thermistor 1 C through self heat generation under stable temperatures. Dissipation factor is the reference value when mounted on a glass epoxy board (1.6 mmT).
