摘要:
The covering sheet includes at least one magnetic material layer made of a resin compound having an oxide magnetic material or a metal magnetic material mixed therein, a ground conductor layer laminated on one surface of the magnetic material layer, and a plurality of via holes for passing conducting unit for grounding the ground conductor layer, or includes a laminate consisting of at least one magnetic material layer made of a resin compound having an oxide magnetic material or a metal magnetic material mixed therein and at least one dielectric layer having a permittivity lower than that of the magnetic material layer, and a ground conductor layer laminated on one surface of the laminate.
摘要:
The invention decreases crosstalk due to capacitive coupling between through type capacitor elements in a multilayer through type capacitor array. On dielectric sheets between electrodes, which constitute a multi capacitor array, through-holes filled with conductive materials are formed, where a central conductor is not present. By electrically connecting conductive materials filled in the through-holes, electrostatic shielding is provided between the through type capacitor elements. Electrical connection is achieved through conductive layers formed outside or inside the through type capacitor elements.
