Abstract
(EN)
A choke coil provided with: a primary coil having a plurality of turns; a secondary coil having a plurality of turns; and an annular core. The choke coil comprises: a multilayer substrate including a first conductor pattern constituting the turns of the primary coil, and a second conductor pattern constituting the turns of the secondary coil; and a conductive base part on which the multilayer substrate and the core are placed. The base part is grounded, the primary coil and the base part are capacitively coupled, and the secondary coil and the base part are capacitively coupled.

L'invention concerne une bobine d'arrêt comportant : une bobine primaire ayant une pluralité de spires ; une bobine secondaire ayant une pluralité de spires ; et un noyau annulaire. La bobine d'arrêt comprend : un substrat multicouche comprenant un premier motif conducteur constituant les spires de la bobine primaire, et un second motif conducteur constituant les spires de la bobine secondaire ; et une partie de base conductrice sur laquelle le substrat multicouche et le noyau sont placés. La partie de base est mise à la terre, la bobine primaire et la partie de base sont couplées de manière capacitive, et la bobine secondaire et la partie de base sont couplées de manière capacitive.
(JA)
複数のターンを有する一次コイルと、複数のターンを有する二次コイルと、環状のコアと、を備えるチョークコイルであって、前記一次コイルの各ターンを構成する第一導体パターンと、前記二次コイルの各ターンを構成する第二導体パターンとを含む多層基板と、前記多層基板と前記コアとが載置される導電性の台部と、を備え、前記台部が、接地されており、前記一次コイルと前記台部とが容量結合され、前記二次コイルと前記台部とが容量結合されているチョークコイル。
