NOTES
1.
BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment)
MIL-STD-217F Notice2 @Ta=25 ºC, Full load (Ground, Benign, controlled environment)
Maximum value at nominal input voltage.
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 negative input.
The LANCUW12 Series can meet EN55022 Class A with an external capacitor in parallel with the input pins.
Recommended: 24Vin: 3.3µF/50V
48Vin: 1.5µF/100V
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, 220uF/100V, ESR 48mΩ.
