NOTES
1. 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 regulation. Operation under no-load condition 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. Chassis Mount Options: No suffix for open frame, “U” suffix for U Channel, and “E” suffix for Enclosed type.
