| 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 |
