Design Reference

1. Ripple & Noise

All the VRB_S-10WR3 series have been tested according to the following recommended test circuit before delivery (see Fig. 2).

The connection of probe to copper foil is shortened as far as possible.

Fig. 2

2. Typical application

If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and Cout or

select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the product.
