摘要： A coil component includes a core including a winding core portion and a first flange portion that is disposed on a first end portion of the winding core portion in a direction in which the winding core portion extends. A first curved portion is formed at a connection between a bottom surface of the winding core portion and the first flange portion. A ratio of a length of the first curved portion in a height direction to a distance in the height direction between the bottom surface and a first terminal electrode is no less than 20% and no more than 60% (i.e., from 20% to 60%).

摘要： An electronic device package includes a molded case and a plurality of leads. The molded case includes integrally formed side walls, end walls, and a top wall, the side walls, end walls and top wall defining an interior for receiving one or more electronic components. Each side wall includes a top portion, an intermediate portion, and a bottom portion. The top portion includes plate-like structure having first and second surfaces extending downward from the top wall. The intermediate portion includes a shelf structure having a shelf surface that extends from the first surface in a direction away from the interior, and a third surface extending downward from the shelf surface.
