Aluminum - Polymer Capacitors

Aluminum - Polymer Capacitors are a type of capacitors made from a combination of aluminum and polymer materials. The materials used vary depending on the purpose for which the capacitor is intended but generally consist of an Aluminum oxide film or a Polymer film etched on a substrate. A typical capacitor will include a dielectric material dielectric layer and electrodes. The dielectric layer, which provides an electrical insulator, is typically made out of Aluminum oxide or Polymer and is generally either formed by chemical deposition on the electrode plates or by physical vapor deposition.
