Note

1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC.

MIL-HDBK-217F Notice2 @Ta=25 ºC, Full load(Ground, Benign, 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. Maximum output deviation is 10% inclusive of remote sense. If remote sense is not being used, the + sense should be connected to its corresponding

+OUTPUT and likewise the –sense should be connected to its corresponding –OUTPUT.

6. Measured with a 1μF M/C and a 10μF T/C.

7. The negative/ positive logic and pin length are optional ( see table ). The pin voltage is referenced to –Vin.

8. Heat sink is optional and P/N: 7G-0021A-F, 7G-0022A-F, 7G-0023A-F, 7G-0024A-F.

9. The HEC50 meets EN55022 class A and class B only with external components connected with the input pins.

10. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5.

The filter capacitor Power Mate suggest: Nippon chemi-con KY series, 220μF/100V, ESR 48mΩ.

11. BASEPLATE GROUNDING：Base-plate should be grounded at one of the four screw bolts prior to operation.

12. The converter is provided by basic insulation.
