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.
