DESCRIPTION
The JFCW series of single and dual output DC DC converters provide up to 15 watts output power in an
industry standard package and footprint. These units are specifically designed to meet power needs in a low
profile package. All models feature a 4:1 wide input voltage range of 9~36VDC or 18~75VDC. Some
features include positive or negative remote on/off, 1600VDC I/O isolation, and trimmable output voltage. All
models are protected against over current, over voltage, input under voltage, and short circuit conditions.

Typical value at nominal input voltage and no load.
Test by minimum input and constant resistive load.
Typical value at nominal input voltage and full load.
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 +Vout pin or –Vout pin.
For Heat Sink option add the suffix “HS” to part number (Ex: JFCW48S5-3000HS) (P/N: 7G-0047C-F).
See attached drawings for more details (pg 5-7).
The standard module meets EN55022 Class A and Class B with external capacitors connected in parallel to the input pins.
Recommended: 24Vin: 6.8µF/50V * 2 pcs 1812 MLCC
48Vin: 2.2µF/100 * 2 pcs 1812 MLCC
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
This product is Listed to applicable standards and requirements by UL.
*Due to advances in technology, specifications subject to change without notice.
Caution:
This power module is not internally fused. An input line fuse must always be used.
