Rated Maximum Power Dissipation : The maximum power that can be continuously applied at the rated ambient temperature.
· 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.
½2
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).
