摘要:
A feed-through capacitor has layers of dielectric material and a first hole that passes through the layers of dielectric material for receiving an electrical conductor connected to the filter capacitor. First, second and third electrodes are disposed between layers of the dielectric material and extend in a first direction substantially perpendicular to a centerline of the first hole. The third electrodes are disposed intermediate the first and second electrodes. Any one of the first, second and third electrodes is non-overlapping with any of another of the first, second and third electrodes in a direction substantially parallel to the centerline of the first hole. A filtering capacitor is formed substantially wholly by fringe-effect capacitance between the first and third electrodes, and a coupling capacitor is formed substantially wholly by fringe-effect capacitance between the second and third electrodes. The filtering and coupling are electrically connected in series.
