单次浪涌性能
Enhanced Film Power MELF Resistor-EFP series,is showing the surge performance from 1uS to 1S.
浪涌功率降额曲线
• 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 1.18% per °C. • For applicable surge power in continuous-surge applications please see SURGE POWER DERATING CURVE above.
