摘要： A package substrate that includes: an inductor layer having a magnetic body and inductor wires. The magnetic body includes a first magnetic layer and a second magnetic layer on at least one main surface of the first magnetic layer. The inductor wires are in the first magnetic layer and include a first wire and a second wire adjacent to each other and magnetically coupled. The second magnetic layer overlaps the first wire and the second wire in a thickness direction. The second magnetic layer has anisotropic magnetic permeability in which magnetic permeability in a main surface direction differs from the thickness direction. The magnetic permeability of the second magnetic layer in the main surface direction is higher than in the thickness direction. The magnetic permeability of the second magnetic layer in the main surface direction is higher than magnetic permeability of the first magnetic layer in a main surface direction.

摘要： An inductor having a coaxial structure is described. In one example, the structure of the single-turn inductor can include a conductor, an insulation layer, a shielding layer, and a magnetic core. An air duct can be located between the shielding layer and the magnetic core. The shielding layer and the magnetic core can both be connected to a ground. In one example, the single-turn inductor can include a single-layer termination structure formed on terminations of the shielding layer. In another example, the single-turn inductor can include a double-layer termination structure formed on terminations of the shielding layer. Displacement current in the single-turn inductor can be reduced using, for example, lumped equivalent circuit models, a semi-conductive shielding layer model, or a resistive layer and conductive shielding layer model.

摘要： A multilayer inductor includes: an element body having a pair of end surfaces facing each other, and a side surface extending in a facing direction of the pair of end surfaces in such a way as to connect the pair of end surfaces; and a through conductor disposed inside the element body and extending in the facing direction. The element body includes a first portion surrounding the through conductor and a second portion positioned outward of the first portion, when viewed in the facing direction. The first portion is disposed spaced from the side surface. The first portion and the second portion have different magnetic permeabilities from each other.

摘要： A winding core includes, for example, four planes, that is, a top surface, a bottom surface, a first side surface, and a second side surface around its central axis. A first wire and a second wire are wound around the winding core in the same direction and have a twisted section. In the twisted section in a plurality of turns at the top surface, bottom surface, first side surface, and second side surface, both the first wire and the second wire are in close contact with each of the ridges between the top surface, bottom surface, first side surface, and second side surface.
