NOTES

1.

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

MIL-HDBK-217F Notice2 @Ta=25 ºC, Full load (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.

Trimming allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting an

external resistor between the TRIM pin and either the +Vout pin or the –Vout pin.

7.

The ON/OFF control pin voltage is referenced to -Vin. (See the “Product Standard Table” below for suffix options).

8.

Heat Sink is optional. Consult factory for ordering details.

9.

The JFC Series can meet EN55022 Class A with external capacitors connected in parallel to the input pins.

Recommended: 12Vin: 10uF/25V

24Vin: 6.8uF/50V

48Vin: 2.2uF/100 * 2 pcs

10.

An external filter capacitor is required if the module has to meet EN61000-4-5. The filter capacitor Wall Industries suggests: Nippon

chemi-con KY Series, 220µF/100V, ESR 48mΩ.
