Patent number: 10205429Abstract: An object is to provide an output-noise reduction device that can prevent noise from an electronic device accommodated in a metal casing from being transmitted due to electromagnetic coupling. An output voltage is extracted to the outside through a conducting bar. A magnetic body core includes a through hole through which the conducting bar is inserted. A chip capacitor is mounted on a mounting board and connects between the output terminal VO and ground potential. A section from the output terminal VO to at least part of the chip capacitor mounted on the mounting board is isolated from the electromagnetic coupling from the electronic device. Thus, noise is prevented from being transmitted to the output terminal VO.Type: GrantFiled: September 21, 2016Date of Patent: February 12, 2019Assignee: KITAGAWA INDUSTRIES CO., LTD.Inventors: Tomokazu Tanimizu, Kazushige Ueno, Katsuyuki Morita, Yoshinori Ohashi

Patent number: 10200005Abstract: An object is to provide an output-noise reduction device in which a component encapsulated through insert molding can be appropriately protected. In a noise filter module (output-noise reduction device), a conducting bar and a magnetic body core are protected with a molded member formed through insert molding. The molded member is formed of a resin material with a molding shrinkage rate of 0.5% or less. Thus, the amount of shrinkage after the molded member is molded and stress as a result of the shrinkage can be made small, whereby damage on the magnetic body core, deformation of a lead frame, and the like can be prevented from occurring.Type: GrantFiled: September 20, 2016Date of Patent: February 5, 2019Assignee: KITAGAWA INDUSTRIES CO., LTD.Inventors: Tomokazu Tanimizu, Kazushige Ueno, Katsuyuki Morita
