Title (EN) INDUCTOR
(FR) BOBINE D'INDUCTANCE
(JA) インダクタ
Abstract: front page image
(EN)An inductor using a rectangular wire wound in an axial direction roughly parallel with a mounted substrate, and enabling an increase in connection strength in mounting. The inductor (10) comprises a core member (20) formed of a magnetic material, the rectangular wire (30) formed in a flat shape so that the contact faces thereof are positioned along the longitudinal direction and forming winding structures (31) by winding them on the outer peripheral surface of the core member (20) by edgewise winding, and a case body (40) in which the core member (20) and the rectangular wire (30) are disposed. The rectangular wire (30) is wound, by multiple turns, on the core member (20), and the multiple winding structures (31) are disposed, in a stacked state, along the axial direction of the core member (20).
(FR)Une bobine d'inductance utilisant un fil rectangulaire bobiné dans une direction axiale grossièrement parallèle à un substrat monté, et permettant une augmentation de la résistance à la connexion lors d'un montage. La bobine d'inductance (10) comprend un élément de noyau (20) constitué d'un matériau magnétique, le fil rectangulaire (30) façonné en une forme plate de telle sorte que les faces de contact de celui-ci soient positionnées le long de la direction longitudinale et forment des structures de bobinage (31) en les bobinant sur la surface périphérique extérieure de l'élément de noyau (20) en réalisant un bobinage de champ, ainsi qu'un corps de boîtier (40) dans lequel sont placés l'élément de noyau (20) et le fil rectangulaire (30). Le fil rectangulaire (30) est bobiné, en multiples spires, sur l'élément de noyau (20) et les structures multiples de bobinage (31) sont disposées empilées le long de la direction axiale de l'élément de noyau (20).
(JA) 平角線が用いられ、かつ巻回の軸線方向が実装される基板に対して略平行を為すインダクタにおいて、実装における接合強度を向上させる。  インダクタ10は、磁性材料から構成されるコア部材20と、接触面が長手に沿う扁平形状を為すと共に、コア部材20の外周面に対してエッジワイズ巻きで巻回されることにより巻回構造31が形成される平角線30と、コア部材20および平角線30が配置されるケース体40と、を具備している。ここで、平角線30は、コア部材20に対して複数巻回されると共に、該複数の巻回構造31がコア部材20の軸線方向に沿って重ねられる状態で配置されている。
