BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC.
MIL-HDBK-217F Notice2 @Ta=25 ºC, Full load(Ground, Benign, controlled environment)
Maximum value at nominal input voltage and full load.
Typical value at nominal input voltage and no load.
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.
