Notes
1. Bellcore TR-NWT-00032, Case: 50% Stress, Temperature at 40°C. MIL-STD-217F Notice 2 @ Ta = 25°C, Full load (Ground, Benign, controlled environment).
2. Maximum value at normal 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.
7. Heat sink is optional and P/N: 7G-0011C-F
8. The MWB30 series can meet EN55022 Class A with external L-C filter before the input pins to the converter. Recommend: 24 Vin : C1=2.2 μ F/50V 1210 MLCC. 48 Vin : C1=2.2 μ F/100V 1210 MLCC.
9. An external input filter capacitor is required if the module has to meet EN61000-4-4. EN61000-4-5. The filter capacitor Polytron Devices suggest: Nippon chemi-con KY series, 220μ F/100V, ESRΩ
