Patent number: 8179658Abstract: A discoidal feedthrough capacitor has its active electrode plates disposed within a dielectric body so that an edge of the active electrode plates is exposed at a surface of a through-hole for a conductive lead. The conductive lead is conductively coupled to the exposed edge of the electrode plates without an intervening conductive termination surface. Similarly, a ground electrode plate set of the feedthrough capacitor may have an edge exposed at the outer periphery of the capacitor for conductively coupling the exposed edge of the ground electrode plate to a conductive ferrule without an intervening conductive termination surface.Type: GrantFiled: September 21, 2009Date of Patent: May 15, 2012Assignee: Greatbatch Ltd.Inventors: Richard L. Brendel, Robert A. Stevenson, Jason Woods

Publication number: 20110002081Abstract: A method that employs a novel combination of conventional fabrication techniques provides a ceramic short-resistant capacitor that is bendable and/or shapeable to provide a multiple layer capacitor that is extremely compact and amenable to desirable geometries. The method allows thinner and more flexible ceramic capacitors to be made. The method includes forming a first thin metal layer on a substrate; depositing a thin, ceramic dielectric layer over the metal layer; depositing a second thin metal layer over the dielectric layer to form a capacitor exhibiting a benign failure mode; and separating the capacitor from the substrate.Type: ApplicationFiled: July 6, 2009Publication date: January 6, 2011Applicant: DELPHI TECHNOLOGIES, INC.Inventors: RALPH S.
