|---|---|
| Nominal Resistance Tolerance | 5%, 10% |
| Climatic Category | 55/155/21 |
| Low Air Pressure | 8.5kpa |
| Stability Grade | 5% |
| Limit Value of Resistance Change | 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 strike resistance type: 35001500 ppm |
| Rated Current | I2(A)=P(W)/R() |
| Power Derating Curve | See Figure 2. Rated power is the maximum value for continuous operation at 70. Derating is required above 70 according to the curve. |
| Fusing Characteristics | 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 applying overload to fusing. |
| Fusing Time Requirements | Under specified rated current multiples overload conditions, fusing time should comply with tables. (See Tables 3-1, 3-2, 3-3 for details). Fusing time can be customized. |
| Impact Resistance | Test involves repeatedly switching on/off for 100 cycles (2s on, 2s off) without open circuit. (See Figure 3 for circuit diagram). Capacitor C and resistor R values are based on customer requirements. |
