What is a film/foil capacitor?

Film/foil capacitors or metal foil capacitors are made with two plastic films as the dielectric. Each is layered with a thin metal foil, usually aluminum, as the electrodes. Advantages of this construction type are easy electrical connection to the metal foil electrodes, and its ability to handle high current surges.

What is the dissipation factor of film/foil capacitors?

The dissipation factor for film/foil capacitors is lower than for metallized film capacitors, due to lower contact resistance to the foil electrode compared to the metallized film electrode. The dissipation factor of film capacitors is frequency-, temperature- and time-dependent.

What is the capacitance of a plastic film capacitor?

The film/foil variants of plastic film capacitors are especially capable of handling high and very high current surges. Typical capacitance values of smaller film capacitors used in electronics start around 100 picofarads and extend upwards to microfarads.

The role of chip integrated capacitors

It is formed by two parallel metal layersand has a high k-dielectric between them. The button layer forms a small parasitic cap with the substrate. This type is the most widely used, because of the high capacitance per area unit with the lowest parasitics. The drawback is that they require more process steps during the. . They are very similar to the MIMs caps but with an oxide layer between metals is usually made by interdigiating metal layers with the process oxide. So the capacitance is created in two places:. . Transistors can be used as a cap using the thin oxide layer from the gate as an insulator. The Gate acts as the top plate and the Drain and Source. . This kind of caps are still an object of study and development. Deep narrow pores are made in the silicon substrateto gain more surface and create high-density capacitor saving die area. These are useful to save area,. . They use only one metal layer, relying on the side capacitance propertyand the matching is better than the MIMs caps. For example, in X-FAB. [pdf]
