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
- 65°C to +175°C. They must be derated according to the following
curves:
