LOAD LIFE SHIFT DUE TO POWER AND DERATING (AT +70 °C AND AT +125 °C)
The power rating for the CMF parts is tied to the derating temperature, the heat rise of the parts, and the R for the load life performance.
When the tables/graphs below are used together they show that when the parts are run at their higher power ratings, the parts will run hotter,
which has the potential of causing the resistance of the parts to shift more over the life of the part.

CMF resistors have an operating temperature range of -55 °C to +175 °C. They must be derated at high ambient temperatures according to
the derating curve.
Example:
When a CMF55 part is run at 1/8 W in a 70 °C ambient environment, the resistor will generate enough heat that the surface temperature of
the part will reach about 19 °C over the ambient temperature, and over the life of the part this could cause the resistance value to shift up to
± 0.15 %.
If the same resistor was instead run at 1/4 W in a 70 °C environment, the element will heat up to about 30 °C over ambient, and over the life
of the part the resistance value could shift roughly ± 0.5 %.
And if the resistor was run at it maximum power rating of 1/2 W in a 70 °C environment, it will heat up to about 58 °C over ambient, and you
could see the resistance value shift roughly ± 1 % over the life of the part.
