1 Rated Maximum Power Dissipation : The maximum power that can be continuously applied at the rated ambient temperature.
· The Maximum Power Dissipation under ambient temperature 25 °C or less is the same with the rated maximum power dissipation, and Maximum
power dissipation beyond 25 °C depends on the Decreased power dissipation curve.
· Please see “Operating Power” for details paging 158.
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).
