BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40C. (Ground fixed and controlled environment). Maximum value at nominal input voltage and full load of standard type. 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. The LANCW8 Series can meet EN55022 Class A with an external capacitor in parallel with the input pins. Recommended: 12Vin: 4.7F/25V 24Vin: N/A. 48Vin: N/A. An external filter capacitor is required if the module has to meet EN61000-4-5. The filter capacitor Wall Industries suggests: Nippon chemi-con KY Series, 220F/100V, ESR 48m. 8.
