Solderability: Continuous satisfactory coverage when tested in accordance with MIL-R-10509 and MIL-R-22684. MATERIAL SPECIFICATIONS Core: Fire-cleaned high purity ceramic. Element: Nickel-chrome alloy. Coating: Flame retardant epoxy, formulated for superior moisture protection. Termination: Standard lead material is solder-coated copper, solderable and weldable. ENVIRONMENTAL SPECIFICATIONS General: Environmental performance is shown in the Environmental Performance table. Test methods are those specified in MIL-R-10509 and MIL-R-22684. Shelf Life: Resistance shifts due to storage at room temperature are negligible. APPLICABLE MIL-SPECIFICATIONS MIL-R-10509 and MIL-R-22684: The CMF madels meet or exceed the electrical, environmental and dimensional requirements of MIL-R-10509 and MIL-R-22684. Noise: Dale metal film resistors have exceptionally iow 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. Voltage Coefficient: Maximum voltage coefficient is 5PPM per volt when measured between 10% and full rated voltage. Dielectric Strength: 450 VAC for CMF-50, CMF-55 and CMF-60. 500 VAC for CMF-07. 700 VAC for CMF-20. 900 VAC for CMF-65 and CMF-70. Insulation Resistance: 10,000 Megohm minimum dry; 100 Megohm minimum after moisture test.
