Publication number: 20150371757Abstract: A multilayer body is a lamination of a plurality of substantially rectangular insulating layers and has a bottom surface being a series of the outer edges of the insulating layers, an end surface being adjacent to the bottom surface and being a series of the outer edges of the insulating layers, and a side surface located on a negative side in the y-axis direction. An outer electrode is embedded in the multilayer body such that it is exposed while extending across the boundary between the bottom surface and the end surface. A coil is disposed in the multilayer body and is connected to the outer electrode. The distance between the outer electrode and the side surface in the corner between the bottom surface and the end surface is longer than the distance between the outer electrode and the side surface where the outer electrode and the coil are connected.Type: ApplicationFiled: August 27, 2015Publication date: December 24, 2015Applicant: MURATA MANUFACTURING CO., LTD.Inventor: Kaori TAKEZAWA

Patent number: 9058927Abstract: A laminate formed by laminating a plurality of insulator layers. First coil conductors are provided in the laminate winding in a predetermined direction when viewed in a plan view in a direction of lamination. Second coil conductors are provided in the laminate on one side in the direction of lamination relative to the first coil conductors, winding in the predetermined direction when viewed in a plan view in the direction of lamination. First via-hole conductors connect downstream ends of the first parallel portion in the predetermined direction. Second via-hole conductors connect downstream ends of the second parallel portions in the predetermined direction. A third via-hole conductor connects the farthest of the first coil conductors on one side to the farthest of the second coil conductors on the other side in the direction of lamination. The first through third via-hole conductors are not connected in a series.Type: GrantFiled: February 20, 2014Date of Patent: June 16, 2015Assignee: Murata Manufacturing Co., Ltd.Inventor: Kaori Takezawa

Publication number: 20150009003Abstract: An electronic component has a laminate including a plurality of laminated insulator layers, the laminate having a top surface and a mounting surface positioned in a first direction perpendicular to a direction of lamination. The direction of lamination is a direction in which the plurality of the insulator layers are laminated. First and second external electrodes are positioned on the mounting surface rather than on the top surface. The first and second external electrodes including first and second Ni-plating films and first and second Sn-plating films provided thereon, respectively. A first total thickness of the first Ni-plating film and the first Sn-plating film and/or a second total thickness of the second Ni-plating film and the second Sn-plating film are/is 11.6 ?m or more, respectively. The first and/or second Ni-plating films are/is 1.37 times or more as thick as the first and/or second Sn-plating films, respectively.Type: ApplicationFiled: June 4, 2014Publication date: January 8, 2015Applicant: MURATA MANUFACTURING CO., LTD.Inventors: Takeru OZAWA, Kaori TAKEZAWA

Patent number: 8514049Abstract: This disclosure provides an electronic component that can suppress a decrease in the resonant frequency. The electronic component includes a multilayer body having plural insulating layers stacked in a staking direction. Outer electrodes are provided on facing lateral sides of the multilayer body and extend in the stacking direction. Coil conductors are stacked together with the insulating layers to form a coil. The thickness in the stacking direction of at least one of the coil conductors that is directly connected to one of the outer electrodes is smaller than that of the coil conductors that are not directly connected to any of the outer electrodes.Type: GrantFiled: April 13, 2011Date of Patent: August 20, 2013Assignee: Murata Manufacturing Co., Ltd.Inventors: Shinichiro Sugiyama, Kaori Takezawa, Hiromi Miyoshi, Masayuki Yoneda

Patent number: 8072306Abstract: A multilayer body is formed by laminating multiple insulating layers. External electrodes are provided on the opposed side surfaces of the multilayer body and extend in the z axis direction. Coil conductors are laminated together with the insulating layers and form a coil. Coil conductors other than coil conductors connected to the external electrodes are made up of pairs of adjacent coil conductors having an identical shape, and coil conductors forming each pair are connected in parallel to each other. None of the coil conductors connected to the external electrodes is connected in parallel to coil conductors with an identical shape.Type: GrantFiled: October 19, 2009Date of Patent: December 6, 2011Assignee: Murata Manufacturing Co., Ltd.Inventors: Shinichiro Sugiyama, Kaori Takezawa, Hiromi Miyoshi, Masayuki Yoneda
