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.
