Publication number: 20240304374Abstract: An inductor component includes an element body, an inductor wiring, and columnar wirings. The inductor wiring extends parallel to a planar main surface in the element body. The columnar wirings extend in a direction intersecting with the main surface. The inductor wiring includes a pair of pad portions at both end portions of the inductor wiring, and to which the columnar wiring is connected, and a wiring main body which connects the pair of pad portions to each other. The wiring main body includes a maximum point where a cross-sectional area of a cross section orthogonal to a center line of the wiring main body is the maximum and a minimum point where the cross-sectional area of the cross section orthogonal to the center line is the minimum. The cross-sectional area at the maximum point is two or more times greater than the cross-sectional area at the minimum point.Type: ApplicationFiled: March 4, 2024Publication date: September 12, 2024Applicant: Murata Manufacturing Co., Ltd.Inventors: Yoshimasa YOSHIOKA, Kenji TOYOSHIMA, Katsufumi SASAKI

Publication number: 20240304377Abstract: An inductor component includes a rectangular parallelepiped element body containing a magnetic material and having a planar main surface, an inductor wiring, and a plurality of columnar wirings. The main surface has a straight side. The inductor wiring includes a pair of pad portions and a wiring main body. The wiring main body has a parallel part extending parallel to the straight side and adjacent to the side without interposing other parts of the inductor wiring therebetween. A dimension in a direction orthogonal to a center line of the wiring main body and parallel to the main surface in the wiring main body is a width dimension, and a shortest distance from the side to the parallel part when viewed through in a direction orthogonal to the main surface is defined as a specific distance. The specific distance is less than the width dimension of the parallel part.Type: ApplicationFiled: March 5, 2024Publication date: September 12, 2024Applicant: Murata Manufacturing Co., Ltd.Inventors: Yoshimasa YOSHIOKA, Kenji TOYOSHIMA, Katsufumi SASAKI
