ELECTRICAL SPECIFICATIONS
± 5% standard on values 1 ohm and above.
± 10% standard on values below 1 ohm.
Temperature Coefficient:
± 90PPM/° C, below 1 ohm.
± 50PPM/° C, 1 ohm to 9.9 ohm.
± 30PPM/° C, 10 ohm and above.
Dielectric Strength:
1000VAC minimum
Short Time Overload:
Any intermittent duty the applied power can greatly exceed the wattage rating. However, since each pulse application is somewhat unique, the factory should be consulted for specific requirrements.
MATERIAL SPECIFICATIONS
Core: Steatite. Chemically inert - will withstand severe thermal shock and is impervious to moisture.
Element: Highest quality copper-nickel alloy or nickel-chrome alloy, depending on resistance value. Special alloys available upon request.
Coating: Special high temperature silicone.
DERATING
Industrial wirewound resistors have an operating temperature range of - 55° C to + 350° C. They must be derated at high ambient temperatures according to the curve below
