The present disclosure concerns a method of manufacturing an electronic device, where the electronic device includes at least one electronic component with at least one electrical winding, and at least one heat dissipation mass coating, and the method includes inserting the at least one electronic component into a cavity; pouring, before or after the insertion of the electronic component, a heat dissipation mass into the cavity so as to at least partially fill the cavity and at least partially cover the electronic component with the heat dissipation mass; removing the electronic device, namely, the electronic component covered by the heat dissipation mass coating, from the cavity. The present disclosure also concerns an electronic apparatus including at least one electronic device manufactured by the foregoing method.

A coil component includes: a body including one surface and one side surface and the other side surface respectively connected to the one surface and opposing each other; a coil portion disposed within the body; a marker disposed on the one surface of the body; and a coating layer disposed on the one surface of the body to cover the marker, wherein the coating layer includes a light-transmitting resin.

Provided is a power inductor. The power inductor includes a body including metal powder and an insulation material, at least one base provided in the body, at least one coil pattern disposed on at least one surface of the base, and an external electrode disposed on each of at least two side surfaces of the body. At least a portion of the external electrode is made of the same material as the coil pattern.

A laminate includes multiple paper layers, with at least one induction coil comprising first and second sets of windings. Two or more paper layers include the sets of windings comprising an electrically-conductive material. The sets of windings may be distributed throughout the laminate layers and provide good wireless induction charging performance in a compact space.

Thermal conductive bobbin, for a magnetic power unit, made of an injectable and polymerizable thermoplastic composition having a plastic polymer in an amount of between 5% and 15% by weight with respect to the total weight of the composition, an aluminium nanoparticles dispersion in mineral oil in an amount of between 25% and 55% by weight with respect to the total weight of the composition, silicon carbide microparticles between 20% and 45% by weight with respect to the total weight of the composition; and additives up to 10% by weight with respect to the total weight of the composition, and wherein the thermal conductive bobbin has a dielectric rigidity higher than 5 kV/mm.

In the coil component, the external terminal and the metal magnetic powder-containing resin constituting the element body are not in direct contact with each other, and thus high ESD resistance is obtained. That is, even when a high transient voltage is applied between the pair of external terminals, insulation breakdown is less likely to occur, and an improvement in breakdown voltage with respect to the transient voltage can be realized.

In a coil component includes an insulating layer interposed between an external terminal and an element body and formed in an entire region excluding a connection region in a formation region in which the external terminal is formed, even when a high transient voltage is applied between the pair of external terminals, insulation breakdown does not occur or hardly occurs because of the insulating layer.

A coil component is provided. The coil component includes a body having one surface and the other surface, opposing each other, and including a plurality of wall surfaces respectively connecting the one surface and the other surface, a coil portion embedded in the body, first and second external electrodes spaced apart from each other on one surface of the body, and respectively connected to the coil portion, a groove formed continuously along an edge of the other surface of the body, and a stress relieving portion disposed on the other surface of the body to fill at least a portion of the groove.

A split core current transformer (CT) includes a first CT core half and a first housing that houses the first CT core half. The split core CT includes a second core half and a housing that houses the second CT core half. The split core CT includes a first set of bushings configured to flexibly couple the first insulative body to the first housing to maintain contact between faces of the first CT core half and faces of the second CT core half.

An electronic device and associated methods are disclosed. In one example, the electronic device includes a package with integrated inductors. In selected examples, the package includes a core layer having a core thickness and through holes. The package further includes inductor structures within the through holes, such that an inductor structure has a length exceeding the core thickness.
