Title:
インダクタおよびそれを用いた電圧変換器
Document Type and Number:
Japanese Patent JP6947290
Kind Code:
B2
Abstract:
An inductor which avoids heat generation and heat dissipation problems, and has a reduced resistance component, when used in a voltage converter. An inductor is configured with a pair of outer electrodes disposed on both end portions of an element assembly and electrically connected to end portions of conductors. The conductors are made of a flat-type wire having a rectangular cross section, are placed side by side between the end portions, and include cylindrical winding sections, respectively, in which the flat-type wire in a long side direction of the rectangular cross section is wound the number of turns less than one about a thickness direction intersecting with a length direction connecting the pair of end portions along the thickness direction. A heat-dissipating member includes a portion being a partition between the conductors and a portion exposed on the top of an outer surface of the element assembly.
