Typical value at nominal input voltage and full load. Test by minimum Vin and constant resistive load. The ON/OFF control pin voltage is referenced to -Vin. To order negative logic ON/OFF control add the suffix-N (Ex: FED20-48S05W-N) Heat sink is optional and P/N: 7G-0020C-F. The FED20W series can meet EN55022 Class A with parallel an external capacitor to the input pins. Recommend : 24Vin : NA. 48Vin : 1μF/100V 1210 MLCC. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The filter capacitor Power Mate suggest: Nippon chemi-con KY series, 220μF/100V, ESR 48mΩ.
