Ratings
Size code (EIA) 0(0402) 1(0603)
Operating Temperature Range 40 to 150 C
1
Rated Maximum Power Dissipation 66 mW 100 mW
2
Dissipation Factor Approximately 2 mW/C Approximately 3 mW/C
1 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.
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).
