Publication number: 20250054686Abstract: An inductor component includes an element body including an insulator; a coil inside the element body; and a first outer electrode electrically connected to the coil. The element body includes first and second end surfaces opposed to each other in a length direction, first and second main surfaces opposed to each other in a height direction perpendicular to the length direction, and first and second side surfaces opposed to each other in a width direction perpendicular to the length and height directions. The first end surface intersects the first main surface on a first ridge line. The second end surface intersects the first main surface on a second ridge line. The first outer electrode includes a first electrode layer embedded in the element body such that at least part of the first electrode layer is exposed from the element body.Type: ApplicationFiled: July 30, 2024Publication date: February 13, 2025Applicant: Murata Manufacturing Co., Ltd.Inventor: Takeru OZAWA

Publication number: 20240412910Abstract: An inductor component includes an element body made of an insulator and a coil conductor inside the element body. The coil conductor includes conductor patterns on a plurality of respective virtual inner surfaces arranged at intervals in an axial direction of the coil conductor to form a portion of an annular track, and a coupling conductor electrically coupling two adjacent conductor patterns among the conductor patterns. At least one conductor pattern among the conductor patterns includes a first conductor pattern and a second conductor pattern that are arranged in the axial direction and are in contact with each other. In a section including an axis of the coil conductor, a center of the first conductor pattern in a direction orthogonal to the axial direction is present at a position different from a position of a center of the second conductor pattern in the direction orthogonal to the axial direction.Type: ApplicationFiled: April 29, 2024Publication date: December 12, 2024Applicant: Murata Manufacturing Co., Ltd.Inventor: Takeru OZAWA

Publication number: 20240412907Abstract: An inductor component includes an element assembly, a coil conductor inside the element assembly, and an outer electrode on an outer surface of the element assembly and electrically connected to the coil conductor. The element assembly includes a lower surface and a side surface. The outer electrode has a lower portion at the lower surface and a side portion at the side surface continuously with the lower portion. The coil conductor includes conductor patterns which form parts of an annular path on virtual inner surfaces intersecting both the lower and side surfaces and lined up at intervals. When a distance A is a shortest distance between the coil conductor and a boundary portion between the lower and side portions and a distance B is a shortest distance between the coil conductor and an end portion of the lower portion opposite the boundary portion, B/A is from 0.2 to 0.6.Type: ApplicationFiled: April 23, 2024Publication date: December 12, 2024Applicant: Murata Manufacturing Co., Ltd.Inventor: Takeru OZAWA

Publication number: 20240203631Abstract: An inductor component includes an element body, a coil inside the element body and spirally wound along a coil axial direction, a first outer electrode electrically connected to one end portion of the coil and exposed on a surface of the element body, and a second outer electrode electrically connected to the other end portion of the coil and exposed on the surface of the element body. The element body includes an insulator. The coil is formed by electrically connecting a plurality of coil wires laminated in the coil axial direction. The coil wires include a first coil wire electrically connected to the first outer electrode with at least one first extended wire interposed therebetween, and a dimension of each of the at least one first extended wire in the coil axial direction is smaller than a dimension of the first coil wire in the coil axial direction.Type: ApplicationFiled: October 18, 2023Publication date: June 20, 2024Applicant: Murata Manufacturing Co., Ltd.Inventors: Takeru OZAWA, Atsushi SEKO, Seiya KIKUCHI

Patent number: 9601259Abstract: 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: GrantFiled: June 4, 2014Date of Patent: March 21, 2017Assignee: Murata Manufacturing Co., Ltd.Inventors: Takeru Ozawa, Kaori Takezawa
