JFCW20

The JFCW20 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 4:1 ultra wide input voltage ranges of 9-36VDC and 18-75VDC. 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 & safety
Notes: 1. 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 pn.
2. The ON/OFF control pin is referenced to –Vin. To order Negative Logic Remote ON/OFF add the suffix “R” to the model number.
3. Heatsink is optional and P/N: 7G-0047C-F. See “Model Number Setup” on page 4 for more information.
4. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The suggested filter capacitor is Nippon chemi-con KY series, 220µF/100V.
CAUTION: This power module is not internally fused. An input line fuse must always be used.
*Due to advances in technology, specifications subject to change without notice.
