    ... Depending on the conditions of the printed circuit board, mount an additional electrolytic capacitor between the power supply and GND terminal. For EMI protection effective to put ferrite beads in the origin of power supply to be fed to BU3058FV from the printed circuit board or to insert a capacitor (of 1 or less), which bypasses high frequency desired, between the power supply and the GND terminal ...
