Single Surge Performance
Metal Film MELF Precision Resistor-MMP series, is showing the surge performance from 10uS to 1S.
Surge Power Derating Curve
• 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 linearly down to zero at 125°C. • For applicable surge power in continuous-surge applications please see SURGE POWER DERATING CURVE above.
