要のピツチで多数列配列した下側リードを所要の
間隔を配して左右対称に対設し、左右の折曲溝に
は角環状のコアの左右の縦側部をそれぞれ嵌挿し
、該コアを上下に挟んでそれぞれの下側リードに
対してコイルを形成するように所要幅の薄平板を
所要勾配で多数列配列し、前後に電極板を一体と
した上側リードを溶着連接してコモンモード巻線
を成形し、該巻線を有するコイルを樹脂層に封入
して成るコモンモードチヨークコイル。 The lower leads, which are made by bending a thin flat plate of the required width into a U-shape and are arranged in multiple rows at the required pitch, are placed symmetrically opposite each other at the required intervals. The left and right vertical sides of a rectangular annular core are inserted into each other, and a large number of thin flat plates of a desired width are arranged at a desired slope so as to sandwich the core vertically and form a coil for each lower lead, A common mode York coil is made by forming a common mode winding by welding and connecting upper leads with integrated electrode plates at the front and back, and enclosing the coil having the winding in a resin layer.
