Title
(EN) COMMON MODE INDUCTOR AND PRODUCTION PROCESS THEREFOR
(FR) INDUCTEUR EN MODE COMMUN ET SON PROCÉDÉ DE PRODUCTION
(ZH) 一种共模电感器及其生产工艺
Abstract
(EN)
Disclosed in the present application are a common mode inductor and a production process therefor. The common mode inductor comprises an integrally formed magnet, and a coil set configured to transmit a signal, wherein the magnet is formed by baking and curing magnetic powder; and the coil set is wrapped inside the magnet. The common mode inductor is small in size, simple in structure, convenient in manufacturing, and good in electromagnetic interference shielding and suppression effects.
(FR)
La présente invention concerne un inducteur en mode commun et son procédé de production. L'inducteur en mode commun comprend un aimant formé d'un seul tenant, et un ensemble bobine configuré pour transmettre un signal, l'aimant étant formé par cuisson et durcissement de poudre magnétique ; et l'ensemble bobine étant enroulé à l'intérieur de l'aimant. L'inducteur en mode commun est de petite taille, de structure simple, pratique à fabriquer et présente de bons effets de suppression et de protection contre les interférences électromagnétiques.
