NOTES
1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC.(Ground fixed and controlled environment)
2. Maximum value at nominal input voltage and full load of standard type.
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. The LANCW12 Series can meet EN55022 Class A with parallel an external capacitor to the input pins.
Recommended: 12Vin: 6.8µF/50V
24Vin: 4.7µF/50V
48Vin: 2.2µF/100V
8. An external filter capacitor is required if the module has to meet EB61000-4-5. (The filter capacitor Wall Industries suggests: Nippon
chemi-con KY Series, 220µF/100V, ESR 48mΩ).
