Title
(EN) NOISE FILTER
(FR) FILTRE DE BRUIT
(JA) ノイズフィルタ
Abstract
(EN)
In order to maintain the noise filter damping effect up to higher frequencies and to enable preventing high temperatures in the noise filter, ground patterns (19a), (19b), (24a), (24b) of ground conductors (19), (24) are arranged extending outside of a winding pattern, in positions (29)-(32) corresponding to the input-output terminal positions (3), (6), (14), (18) of the winding pattern of a winding conductor (100), and in the ground patterns (19a), (19b), (24a), (24b) of the ground conductors, slits (20)-(23), (25)-(28) are provided which divide portions arranged around a magnetic core (400).
(FR)
Selon l’invention, l’effet atténuation d’un filtre de bruit est préservé jusqu’à une haute fréquence, et simultanément il est possible d’empêcher le filtre de bruit d’atteindre une température élevée. Des motifs de terre (19a, 19b, 24a, 24b) de conducteurs de terre (19, 24) sont placés de manière à s’étirer côté extérieur d’un motif d’enroulement en des positions (29)~(32) s’opposant à des positions de bornes d’entrée et sortie (3, 6, 14, 18) d’un motif d’enroulement d’un conducteur d’enroulement (100), et des fentes (20)~(23) et (25)~(28)qui partagent une section disposée autour d’un noyau de corps magnétique (400), sont agencées sur les motifs de terre (19a, 19b, 24a, 24b) des conducteurs de terre.

 ノイズフィルタの減衰効果を高周波まで維持させるとともに、ノイズフィルタが高温になるのを防止させることができるものを得る。グラウンド導体(19)、(24)のグラウンドパターン(19a)、(19b)、(24a)、(24b)が巻線導体(100)の巻線パターンの入出力端子位置(3)、(6)、(14)、(18)に対向する位置(29)~(32)において、巻線パターンの外側に延伸されて配設されており、グラウンド導体のグラウンドパターン(19a)、(19b)、(24a)、(24b)には、磁性体コア(400)の周りに配置される部分を分断するスリット(20)~(23)、(25)~(28)が設けられている。
