Embodiments of the disclosure relate to apparatuses for enhanced thermal management of an inductor assembly using functionally-graded thermal vias for heat flow control in the windings of the inductor. In one embodiment, a PCB for an inductor assembly includes a top surface and a bottom surface. Two or more electrically-conductive layers are embedded within the PCB and stacked vertically between the top surface and the bottom surface. The two or more electrically-conductive layers are electrically connected to form an inductor winding. A plurality of thermal vias thermally connects each of the two or more electrically-conductive layers to a cold plate thermally connected to the bottom surface. A number of thermal vias thermally connecting each electrically-conductive layer to the cold plate is directly proportional to a predetermined rate of heat dissipation from the electrically-conductive layer.

The subject matter described herein provides systems and techniques for the integration of TLVR technology in a vertical power VR module. A multiple-secondary TLVR topology using a controlled leakage inductance in the place of a separate compensation inductor, Lc, may be employed for the vertical power VR module. In addition, the capacitance inside the device to which the TLVR based vertical power VR module supplies power, rather than an output capacitance board, may be used in order to allow the module to be a single layer. Example structures that may include one or more primary windings and/or one or more secondary windings for each of possibly multiple linked phases of the TLVR based module are provided. The windings may be formed using traditional copper windings or printed circuit board (PCB) copper trace winding.

An electronic component preventing peeling of an external terminal is provided. Since each of the external terminal electrodes on the upper face has a U-shaped outline, stress concentration is less likely to occur at an inner end portion than in the external terminal electrode having a corner at the inner end portion. Therefore, for example, even when an impact is applied, a situation in which the external terminal electrode peels off from the upper face due to stress concentration is prevented.

A coil component includes: a body; a coil unit including lead-out ends and coils, and embedded in the body; and a core penetrating through the coil unit in a first direction, wherein a cross-section of each of the coils perpendicular to a direction in which the coil is wound has a plurality of round portions disposed on a side facing the core.
