POWER RATING
Power ratings are based on the following two conditions:
1. ± 2.0% maximum R in 10000 hours load life.
2. + 175°C maximum operating temperature.
APPLICABLE MIL-SPECIFICATIONS
MIL-PRF-55182:
The ERC series meets the electrical, environmental and
dimensional requirements of MIL-PRF-55182.
MIL-PRF-10509:
MIL-PRF-55182 supercedes MIL-PRF-10509 on new designs.
The ERC series meets or exceeds MIL-PRF-10509
requirements.
Documentation: Qualification and failure rate verification
test data is maintained by Vishay Dale and is available upon
request. Lot traceability and identification data is maintained
by Vishay Dale for five years.
Vishay Dale ERC resistors have an operating temperature
range of - 65°C to + 175°C. They must be derated according to
the following curve:
Element: Vacuum-deposited nickel-chrome alloy Encapsulation: Specially formulated epoxy compound
Standard lead material is solder-coated copper
Core: Fire-cleaned high purity ceramic Termination: Solderable and weldable per
MIL-STD-1276, Type C.
