BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment). 2. Maximum value at nominal input voltage and full load. 3. Typical value at nominal input voltage and no load. 4. Typical value at nominal input voltage and full load. 5. Test by minimum Vin and constant resistive load. 6. The output requires a minimum loading to maintain specified regulations. Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications. 7. The ON/OFF control pin voltage is reference to -Vin. 8. Heat-sink is optional, please contact factory for ordering details. 9. An external filter capacitor is required if the module has to meet EN61000-4-5. The filter capacitor suggested is Nippon chemi-con KY Series, 220μF/100V, ESR 48mΩ.
