浪涌功率降额曲线
1. Above graph is accurate for NON REPETITIVE applications operating in an ambient temperature of 70°C or less. For temperatures above 70°C, the graph power must be derated further by 0.62% per °C until 200°C.
2. For applicable surge power in continuous-surge applications please see SURGE POWER DERATING CURVE.
