General Data
| Nominal Resistance Tolerance: | 5%, 10% |
| Climatic Category: | 55/155/21 |
| Low Air Pressure: | 8.5kPa |
| Stability Grade: | 5% |
| Resistance Change Limit: | Long-term Test: (5%R+0.1); Short-term Test: (1%R+0.05) |
| Temperature Coefficient: | Standard Type 350 ppm; Semi-fusible, Explosion-proof, High Lightning Surge Type: 35001500 ppm |
| Rated Current: | I(A) = P(W)/R() |
| Derating Curve: | Rated power is the maximum value for continuous operation at 70. Power derating is required above 70 according to the curve. |
| Fusing Characteristic: | Defined as significant increase in resistance when subjected to specified overload, causing current to drop below 1/50 of the initial test current. Fusing time is the duration from overload application to fusing. |
| Impact Resistance: | Test involves repeated switching for 100 cycles (2s ON, 2s OFF) without open circuit. |
