Note:
BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC.

2. Maximum value at nominal input voltage and full load.
3. Typical value at nominal input voltage and no load.
4. Typical value at nominal input voltage and full load.
5. Test by minimum Vin and constant resistive load.
6. The ON/OFF control pin voltage is referenced to -Vin.
To order positive logic ON/OFF control add the suffix-P (Ex: FEC15-48S05W-P)
To order negative logic ON/OFF control add the suffix-N (Ex: FEC15-48S05W-N)
7. 0perating ambient temperature:
Converter can meet the railway T2 temperature requirement at full load. The operating temperature can up to Ta = 85ºC as power derating from 100%
to 80% for TX requirement.
8. Heat sink is optional and P/N: 7G-0020C-F.
9. EN55022 and EN50155
1) To meet Class A with parallel an external capacitor to the input pins.
Recommend : 24Vin : NA.
48Vin : 1μF/100V 1210 MLCC.
2) To meet Class B please refer to the suggestion filter in next page.
10. 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.
