Power curve
For resistors operating at an ambient temperature of 70°C, the rated power is reduced according to the following curve:
Performance Testing
| Item | Test Method | Judgment Criteria | Standard |
|---|---|---|---|
| Resistance Temperature Coefficient (TCR) | TCR = (R - R0) / R0 * (T2 - T1) * 10^6, where R0 is the resistance at 20°C, R is the resistance at 60°C, T1 is 20°C, T2 is 60°C | - | Refer to specifications |
| Short Time Overload | 5 times rated power for 5 seconds | ≤ ±0.5% | MIL-R-26E |
