General Data
| Parameter | Specification |
|---|---|
| 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-fusing type, explosion-proof type, high lightning surge type: 35001500 ppm |
| Rated Current | I2(A) = P(W)/R() |
| Derating Curve | Rated power is the maximum value for continuous operation at 70. 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 time from overload application to fusing. |
| Fusing Time Requirements | Under specified rated current overload multiples, fusing time must comply with tables (for standard type, high lightning surge type, explosion-proof type, semi-fusing type). Fusing time can be customized. |
| Surge Impact Performance | Test involves repeated closing and opening of a switch for 100 cycles (2S on, 2S off). Resistor should not become open circuit. Capacitor C selection based on customer requirements (default 10uF). Resistor R value selection based on circuit (20W power rating, 0.8 power factor, 5.1K5% for resistors below 10W). |
