A capacitor, which is comprised of a pair of conductive foils each having a dielectric layer on its surface wherein the dielectric layers are attached to one another. In one process for its production a capacitor is formed by applying a first dielectric layer onto a surface of a first conductive foil; applying a second dielectric layer onto a surface of a second conductive foil; and then attaching the first and second dielectric layers to one another. The resulting capacitor exhibits excellent void resistance.

Why it's free to use
- Filed August 7, 2001 and granted June 7, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 7, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 7, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
