the round capacitor is not hard pressed; instead it is left round (Figure 11). Then, depending on whether the Al can is oil-filled or dry-filled, the capacitor goes through a process to place the bound capacitor inside the Al shell and fill with oil or resin. The capacitor, whether resin-filled or dry-filled, must be cured before it is capped off.
How A Capacitor Works
This capacitor also produces an effect called: "tightening the power rails" and effectively acts like a miniature battery with very low impedance supplying current to the chip.
