MATERIAL SPECIFICATIONS ENVIRONMENTAL SPECIFICATIONS Element: Nickel-chrome alloy General: Coating: Flame retardant epoxy, formulated for superior moisture protection Environmental performance is shown in the Environmental Performance table. Test methods are those specified in MIL-R-10509 and MIL-PRF-22684. Core: Fire-cleaned high purity ceramic Shelf Life: Termination: Standard lead material is solder-coated copper Solderable and weldable. Resistance shifts due to storage at room temperature are negligible. 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. Vishay Dale CMF resistors have an operating temperature range of - 65C to +175C. They must be derated according to the following curves: % OF RATED POWER APPLICABLE MIL-SPECS 120 100 MIL-R-10509 Char. D Rating 80 MIL-R-10509 Char.
