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 on the output 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 referenced to –Vin. 8. Heat sink is optional (for operation temperature range please see derating curve). Contact Factory for ordering details. 9. The CMYF Series is 2:1 wide input range of 18-36VDC and 36-75VDC; the CMYFW Series is 4:1 ultra wide input range of 9-36VDC and 18-75VDC. 10. Chassis Mount Options: No suffix for open frame, “U” suffix for U Channel, and “E” suffix for Enclosed type. DERATING CURVES & EFFICIENCY GRAPHS
