L: Simulated source impedance of 12μH C: Nippon chemi-con KMF series, 220μF/100V. The ON/OFF control pin voltage is referenced to –Vin BELLCORE TR-NWT-000332. Case I: 50%. Stress, Temperature at 40ºC. (Ground fixed and controlled environment) An external filter capacitor is required for EMC testing. The capacitor should be capable of handing 1A ripple current for 48V models. Power mate suggest: Nippon chemi-con KMF series, 220μF/100V, ESR 90mΩ. Test condition: nominal input and full load. Maximum value at nominal input voltage and full load. Typical value at nominal input voltage and full load.
