DESCRIPTION
The JFC20 series of DC/DC power converters provides 20 watts of output power in a 1.0 x 1.0 x 0.39 inch industry standard package
and footprint. This series has single and dual output models with 2:1 wide input voltage ranges of 9-18VDC, 18-36VDC, and 36-
75VDC. Some features include high efficiency, ultra low quiescent current, 1600VDC I/O isolation, remote ON/OFF, and trimmable
output voltage. This series is also protected against over voltage, over current, input under voltage, and short circuit conditions. All
models are RoHS compliant and have UL60950-1, EN60950-1, and IEC60950-1 safety approvals.

NOTES
1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40°C.
MIL-HDBK-217F Notice2 @Ta=25°C, 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. 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 is referenced to –Vin. To order Negative Logic Remote ON/OFF add the suffix “R” to the model number.
8. Heatsink is optional and P/N: 7G-0047C-F. See “Product Standard Table” on page 5 for ordering information.
9. EN55022
1) To meet Class A the module needs no external components
2) To meet Class B please refer to the filter suggestion on page 4.
10. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The filter capacitor suggested is Nippon
chemi-con KY series, 220μF /100V, ESR 48mΩ.
11. There are several different options available for this series. Please see the “Product Standard Table” on page 5 for all options and ordering
information.
