General: Environmental performance is shown in the Environmental Performance table. Test methods are those specified in MIL-R-10509 and MIL-PRF-22684. Resistance shifts due to storage at room temperature are negligible.

Flame retardant epoxy, formulated for superior moisture protection Fire-cleaned high purity ceramic Standard lead material is solder-coated copper. Solderable and weldable. Shelf Life:

Vishay Dale CMF resistors have an operating temperature range + 175 �C. They must be derated according to the following curves:

MIL-R-10509 and MIL-PRF-22684: The CMF models meet or exceed the electrical, environmental and dimensional requirements of MIL-R-10509 and MIL-PRF-22684. Noise: Vishay Dale metal film resistors have exceptionally low noise level. Average for standard resistance range is 0.10 micro-volt per volt over a decade of frequency, with low and intermediate resistance values typically below 0.05 micro-volt per volt.

1.0 RN70 NOTE: Commercial equivalents of military styles are available with higher power ratings. Consult factory.

The increase in resistors surface temperature due to rated load is shown in the chart above. Resistor temperature = heat rise + ambient temperature.
