Ceramic-wound-capacitor with lead lanthanum zirconium titanate dielectric
Abstract
A ceramic-wound-capacitor includes a first-electrically-conductive-layer, a dielectric-layer, a second-electrically-conductive-layer, and a protective-coating. The dielectric-layer is formed of lead-lanthanum-zirconium-titanate (PLZT). The protective-coating has a thickness of less than ten micrometers (10 μm) and provides electrical isolation between the first-electrically-conductive-layer and the second-electrically-conductive-layer of the ceramic-wound-capacitor. A method for fabricating the ceramic-wound-capacitor includes the steps of feeding a carrier-strip, depositing a sacrificial layer, depositing a first-electrically-conductive-layer, depositing a dielectric-layer, and depositing a second-electrically-conductive-layer to form an arrangement coupled to the carrier-strip by the sacrificial-layer, separating the arrangement from the carrier-strip and sacrificial-layer, creating an exposed-surface of the first-electrically-conductive-layer, applying a protective-coating to the exposed-surface of the first-electrically-conductive-layer, winding the arrangement with the protective-coating to form a ceramic-wound-capacitor, where the protective-coating is in direct contact with the first-electrically-conductive-layer and the second-electrically-conductive-layer of the ceramic-wound-capacitor.
