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 LANC8UW Series can meet EN55022 Class A with an external capacitor in parallel with the input pins. Recommend: 24Vin: 1µF/50V 48Vin: 0.47µF/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.
