NOTES

(1)

Typical value at nominal input voltage and no load.

(2)

Test by minimum input and constant resistive load.

(3)

Typical value at nominal input voltage and full load.

(4)

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.

(5)

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).

(6)

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

(7)

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 48m

Ω

Caution: This power module is not internally fused. An input line fuse must always be used.
