Tantalum Supply Enters

6electrolytic capacitors are still useful for bulk power supply decoupling typically where power enters a board assembly -- electrolytics generally give more capacitance per unit volume than ceramic and since the power supply system leads already have some series inductance the additional inductance of the electrolytics is.
