**Test ripple and noise by “parallel cable” method. See detailed operation instructions at Testing of
Power Converter section, application notes.
Note:
1.All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output load unless
otherwise specified.
2. See below recommended circuits for more details.

APPLICATION NOTE
Recommended Circuit
All the URA_D-5W & URB_D-5W Series have
been tested according to the following
recommended testing circuit before leaving
factory. This series should be tested under load.
Never be tested under no load (see Figure 1).

If you want to further decrease the output ripple,
you can increase capacitance properly or choose
capacitors with low ESR. However, the
capacitance should not be too high. (Table 1).
