・All specifications are subject to change without notice.
For products other than with 10W, capacitors are not con-
nected between the primary GND and the secondary GND.
To reduce common mode noise, connect a capacitor with
around 1000pF between the primary GND and the second-
ary GND, as shown in the figure below.
In this case, note that if the capacitor that is connected is
too large, coupling capacitance between input and output
becomes large.
Also be careful about the withstand voltage of the capacitor
(500V or over is desirable with consideration of the insula-

For products with 10W, capacitors with 1000pF are inter-
nally connected between primary and secondary.

2-6. Radiation noise
Radiation noise of the converter can be reduced by con-
necting the case terminal to the input or output GND ter-
minal. The effectiveness varies depending on the device.
Check it on the actual device.
Regarding wiring, use GND line and solid pattern for the
bottom of the converter as much as possible.
- SMD models are not equipped with case terminals.

Board cleaning after soldering is not recommended. How-
ever, the cleaning fluids and conditions shown in the table
