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 µV per V
over a decade of frequency, with low and intermediate resistance
values typically below 0.05 µV per V.
CAGE CODE: 91637
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.
Shelf Life Resistance shifts due to storage at room
temperature are negligible.
