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.
