Publication number: 20180374646Abstract: A multilayer ceramic coupling capacitor having a low insertion loss across a wideband frequency range is provided herein. In an example, a multilayer ceramic capacitor (MLCC) includes a body comprising top and bottom surfaces, first and second opposite ends, and electrode and dielectric layers. The MLCC also includes first and second terminals attached to the ends, and main block layer electrodes within the body configured in an alternating manner such that a first of the main electrodes is in electrical communication with the first terminal and extends from one end inwardly, and a next of main electrodes is in electrical communication with the second terminal and extends from an opposite end inwardly. In addition, the MLCC includes a first shield electrode in electrical communication with the first terminal and extending from the first end inwardly, positioned between the main electrodes and a lower surface of the body.Type: ApplicationFiled: June 26, 2018Publication date: December 27, 2018Applicant: VISHAY ISRAEL LTD.Inventors: Brian Ward, Eli Bershadsky, Guy Burshteyn, John Rogers, Oded Shiek

Publication number: 20120300363Abstract: A bulk capacitor includes a first electrode formed of a metal foil and a semi-conductive porous ceramic body formed on the metal foil. A dielectric layer is formed on the porous ceramic body for example by oxidation. A conductive medium is deposited on the porous ceramic body filling the pores of the porous ceramic body and forming a second electrode. The capacitor can then be encapsulated with various layers and can include conventional electrical terminations. A method of manufacturing a bulk capacitor includes forming a conductive porous ceramic body on a first electrode formed of a metal foil, oxidizing to form a dielectric layer and filling the porous body with a conductive medium to form a second electrode. A thin semi-conductive ceramic layer can also be disposed between the metal foil and the porous ceramic body.Type: ApplicationFiled: August 6, 2012Publication date: November 29, 2012Applicant: Vishay Sprague, Inc.Inventors: Reuven Katraro, Nissim Cohen, Marina Kravchik-Volfson, Eli Bershadsky, John Bultitude

Patent number: 7907090Abstract: A dielectric ceramic composition has a dielectric constant, K, of at least 200 and a dielectric loss, DF, of 0.0006 or less at 1 MHz. The dielectric ceramic composition may be formed by sintering by firing in air without a controlled atmosphere. The dielectric ceramic composition may have a major component of 92.49 to 97.5 wt. % containing 60.15 to 68.2 wt. % strontium titanate, 11.02 to 23.59 wt. % calcium titanate and 7.11 to 21.32 wt. % barium titanate; and a minor component of 2.50 to 7.51 wt. % containing 1.18 to 3.55 wt. % calcium zirconate, 0.50 to 1.54 wt. % bismuth trioxide, 0.2 to 0.59 wt. % zirconia, 0.02 to 0.07 wt. % manganese dioxide, 0.12 to 0.35 wt. % zinc oxide, 0.12 to 0.35 wt. % lead-free glass frit, 0.24 to 0.71 wt. % kaolin clay and 0.12 to 0.35 wt. % cerium oxide. UHF antennas and monolithic ceramic components may use the dielectric ceramic composition.Type: GrantFiled: June 7, 2007Date of Patent: March 15, 2011Assignee: Vishay Intertechnology, Inc.Inventors: Eli Bershadsky, Marina Kravchik, Reuven Katraro, David Ben-Bassat, Dani Alon
