Hello,

In the datasheet ,  the  Input Capacitor (after Switching-Bridge) is  0.33-µF Y2/X2 film capacitor.Can aluminum capacitor  in place of it?

    Hello,

    This capacitor is generally and X or Y cap and used for filtering the rectified line voltage and current.  This capacitors is generally a film capacitor  and not a electrolytic capacitor.  I believe this is because the electrolytic capacitors do not handle low frequency AC voltages and current that well.  I would recommend against this.
