A coil component includes a body and external electrodes. The body includes a support member having through-openings formed in end portions thereof, an internal coil supported by the support member, and an encapsulant encapsulating the support member and the internal coil. The through-openings are filled with end portions of the internal coil. An insulating layer is interposed between the internal coil and the external electrode.

A coil component includes a body having one surface and another surface opposing each other in one direction, an internal insulating layer embedded in the body, and a coil portion disposed on the internal insulating layer and forming at least one turn. First and second external electrodes are disposed on the one surface of the body to be spaced apart from each other, and first and second connection electrodes respectively penetrate through the body to connect the coil portion and the first and second external electrodes to each other. A support electrode extends from the coil portion to be exposed to the other surface of the body to support the coil portion and the internal insulating layer.

An inductor component comprising a base body including first and second magnetic layers laminated in order along a first direction; and an inductor wire between the first and second magnetic layers and on a plane that is orthogonal to the first direction. The first magnetic layer is in a reverse direction to the first direction of the inductor wire, the second magnetic layer is in the first direction of the inductor wire and in a direction that is orthogonal to the first direction, and when a main surface of the second magnetic layer is viewed from a direction which is orthogonal to the main surface of the second magnetic layer in the first direction, the second magnetic layer includes a dark region corresponding to the inductor wire and a bright region whose brightness is higher than that of the dark region.

A coil component includes a first alignment winding region in which a second wire is continuously wound so as to have turns such that the turns of the second wire are aligned with turns of a first wire having the same ordinal number outside the first wire in a direction perpendicular to a central axis. The ordinal number is counted from the turn nearest to the first flange portion.

A power system has a power-electronic module that includes a housing defining a looped reservoir, a ferro-magnetic medium sealed within and filling the looped reservoir, and a conductor surrounded by the ferro-magnetic medium. The conductor is coiled within and along the looped reservoir, and has terminals extending out of the reservoir such that the ferro-magnetic medium and conductor form an inductor that opposes changes in magnitude of current flowing through the conductor.

A coil component has a magnetic element body made of resin containing magnetic particles, a coil part embedded in the magnetic element body, conductor posts which are embedded in the magnetic element body and whose one ends are connected to the coil part and the other ends are exposed from the magnetic element body, an insulating layer interposed between the conductor posts and the magnetic element body, and other insulating layers interposed between the coil part and the magnetic element body. Since the insulating layer is interposed between the conductor posts and the magnetic element body, it is possible to ensure insulation performance between the conductor posts and the magnetic element body and to prevent the occurrence of peeling therebetween.

A magnetic inlay includes a magnetic matrix and a plurality of electrically conductive vertical through connections extending vertically through the magnetic matrix. Further, a component carrier including the magnetic inlay and a method of manufacturing said magnetic inlay are described.

A magnetic inlay for a component carrier includes a magnetic matrix and an electrically conductive structure embedded horizontally in the magnetic matrix. The electrically conductive structure is configured as an inductive element. The magnetic inlay is configured so that, depending on the geometrical properties of the electrically conductive structure, a specific inductance value is provided for the magnetic inlay.

A component carrier includes a stack including at least one electrically conductive layer structure and/or at least one electrically insulating layer structure, a magnetic element assembled to the stack, and a dielectric layer structure on the stack. The magnetic element includes an embedded inductive element. The dielectric layer structure at least partially surrounds the magnetic element. Further, a manufacturing method and a use of photo-imaging are described.

An insulating material-coated soft magnetic powder includes: a core particle that includes a base portion containing a soft magnetic material containing Fe as a main component and at least one of Si, Cr, and Al, and that includes an oxide film provided on a surface of the base portion and containing an oxide of at least one of Si, Cr, and Al; and an insulating film that is provided on a surface of the core particle and that contains a ceramic, in which a thickness of the insulating film is 5 nm or more and 300 nm or less, and the oxide contained in the oxide film and the ceramic contained in the insulating film are mutually diffused at an interface between the oxide film and the insulating film.
