Publication number: 20200020486Abstract: A capacitor may include a stack assembly. The stack assembly may include a plurality of anode plate members, each having an embedded wire. The anode plate members may be separated by at least one cathode foil sandwiched between separator sheets. A conducting member may electrically connect the embedded wires and may have an externally accessible end portion that is hermetically sealed from the interior of the capacitor. A case covers the stack assembly and may be attached to a cover. The case and cover may enclose the stack assembly within an interior area of the capacitor. The at least one cathode foil may be connected to the case. An electrolyte fluid may be disposed within the interior area of the capacitor. A passage may be provided through a central portion of the stack assembly. A tube, surrounded by insulation, may pass through the passage and may be connected to the cover and the case.Type: ApplicationFiled: July 16, 2018Publication date: January 16, 2020Applicant: VISHAY ISRAEL LTD.Inventors: Alex Eidelman, Timothy Bishop, Stephen Breithaupt, Matthew Lang, John Van Voorhis, Andrey Mitiagin

Patent number: 8466772Abstract: On the track of a potentiometer a resistive path of thin film is deposited or a foil is bonded to a matched substrate and a parallel path is formed of discrete contact straps extending from the resistive path. The resistive path has a protecting coating and the wiper is moving on abrasion resistant contact straps. This design enables application of high precision and stability resistor technologies in the production of variable resistors destined for long service life. It enables also, in high precision applications, by maintaining the linearity of the output versus input function, a two-wire connection to the variable resistor used as a position sensor.Type: GrantFiled: February 17, 2009Date of Patent: June 18, 2013Assignee: Vishay Israel, LtdInventors: Joseph Szwarc, Jean-Michel Lanot, Ruta Zandman

Patent number: 6529115Abstract: A precision surface mounted foil resistor has a substrate having top and bottom planar surfaces. A resistance foil is secured to the bottom surface of the substrate and extends over the bottom. A bending protector plate of non-conductive material is superimposed over the resistance foil. A solder material is located at two areas of the foil to provide electrical contact with the PCB. The bending protector element is thicker than the solder contact areas and is provided between the solder material.Type: GrantFiled: March 16, 2001Date of Patent: March 4, 2003Assignee: Vishay Israel Ltd.Inventors: Joseph Szwarc, Ilya Aronson
