DESIGN CONSIDERATIONS
1) Recommended circuit
All the URC_D-30WR2 Series have been tested according to the following recommended test circuit before leaving the factory (see Figure 4).
If you want to further decrease the input/output ripple, you can increase a capacitance-values properly or choose capacitors with low ESR, but the
total capacitance of the filter capacitor must not exceed the Max. Capacitive Load.
Recommend external capacitor see table 1.
