The RP20-S_DFW 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 40°C (Ground fixed and controlled environment). 3. Requires external filter to meet EN55022 Class A 4. Typical value at nominal input voltage and no load. 5. Maximum value at nominal input voltage and full load 6. Typical value at nominal input voltage and full load. 7. Test by minimum Vin and constant resistor load. 8. Optional Heatsink Part Number 7G-0020A 9. 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).
