Notes :
RP20-S_DF Series
1. The RP20 series requires a minimum of 10% loading on the output to maintain specified regulation. Operation under no-load condition will not damage these devices, however they may not meet all listed specification. 2. BELLCORE TR-NWT-000332. Case l: 50% Stress, Temperature at 40C (Ground fixed and controlled environment). 3. Simulated source impedance of 12uH. 12uH inductor in series with +Vin. 4. Maximum value at nominal input voltage and full load of standard type. 5. Typical value at nominal input voltage and full load. 6. Test by minimum Vin and constant resistor load. 7. The ON/OFF control function can be positive or negative logic. The pin voltage is referenced to negative input. Positive logic ON/OFF is standard, no suffix (Ex. RP20-2405SF) Negative logic ON/OFF is marked with suffix-N (Ex. RP20-2405SF/N). 8. Heat sink is optional and P/N: 7G-0020A. 9. An external filter capacitor is required for normal operation. The capacitor should be capable of handing 1A ripple current for 48V/24V models. RECOM suggest: Nippon chemi-con KMF series, 220F/100V, ESR 90m . 10.See application notes for EMI-filtering.
