MATERIAL SPECIFICATIONS
Element:
Coating:
Core:
Nickel-chrome alloy
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.
Flame retardant epoxy, formulated for
superior moisture protection
Fire-cleaned high purity ceramic
Standard lead material is solder-coated
copper. Solderable and weldable.
Shelf Life:
Termination:
Vishay Dale CMF resistors have an operating temperature range of
- 65 °C to + 175 °C. They must be derated according to the
following curves:
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.
