MATERIAL SPECIFICATIONS Element: Coating: Nickel-chrome alloy Flame retardant epoxy, formulated for superior moisture protection Fire-cleaned high purity ceramic ENVIRONMENTAL SPECIFICATIONS 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. Core: Termination: Shelf Life: Standard lead material is solder-coated copper. Solderable and weldable. APPLICABLE MIL-SPECS 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 120 100 80 60 40 20 MIL-PRF-22684 MIL-R-10509 Char. D Rating MIL-R-10509 Char.
