The second advantage is a reduction in the number of bypass capacitors required by a design to over come "droop" in the power delivered to an active device. Reducing the number of bypass capacitors obviously results in additional routing space on the outer layers of the board. This can result in a reduction of board size or even innerlayer

The outside foil of a spiral-wrapped film capacitor shields the inner conductor. some have the foils offset axially ("extended foil"), so that the end terminations can short across each layer of their respective plates. Thus electrons never have to flow in a spiral across each wrap. This also makes for better shielding by the outer layer

6 FAQs about [Outer layer wrapped capacitor]
What is the difference between inner foil and outer foil of a capacitor?
Basically, most of the capacitor, has what we call the inner foil and outer foil. Because, most of capacitor’s construction is based on the winding of paper or other conductor (silver, copper, gold, etc), so we will have a start position (the inner foil) and the finish position (the outer foil).
How is a capacitor oriented?
When properly installed, the capacitor will be oriented in such a manner that the outside foil lead is connected to the lowest impedance (usually the ground) side of the circuit. As the Figure 2 schematic shows, the vast majority of capacitors have one lead tied directly to chassis ground.
Are the outer plates used in a capacitor rolled up?
The outer plates are not used. When the capacitor is rolled up with an extra layer of dielectric the outer faces of the two plates are now adjacent to each other, forming a second capacitor in parallel with the inner plates. This is not true for all parts of the "roll."
What is a capacitor lead?
The capacitor lead that is connected to the ‘scope common or coax shield braid (black alligator clip) side when the trace amplitude is at its lowest is the capacitor lead connected to the outer foil. I generally score these leads with a Sharpie® marker once I track them down. So far, this is pretty simple and straightforward, right?
Why do capacitors have a start and finish position?
Because, most of capacitor’s construction is based on the winding of paper or other conductor (silver, copper, gold, etc), so we will have a start position (the inner foil) and the finish position (the outer foil). Although for the film type capacitor, it’s just fine to connect positive or negative to the inner or outer foil.
Are metallized polyester film capacitors marked?
A recent discussion with an engineer at Cornell Dubilier regarding their Illinois Capacitor MWR series of metallized polyester film capacitors confirmed that the MWR capacitors are not marked as to the outside foil lead, regardless of what markings may be on the body of the capacitor.
