MULTILAYER CAPACITOR AND PACKAGING STRUCTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a multilayer capacitor capable of making space saving compatible with low ESL in a condition including an internal structure and a packaging structure, and managing high-density packaging of components, and the packaging structure thereof.SOLUTION: A noise current superimposed on a power line flows through hot-side external electrodes 52a, 52b into a capacitor, passes through a hot-side internal electrode layer 54 connected to a core-shaped conductor 57 penetrating the central parts of layers 54, 55, 56 and a ground-side internal electrode layer 55 opposing the layer 54, and flows through ground-side external electrodes 53a, 53b, 53c, 53d to the outside of the capacitor. In such a case, a plurality of ground-side external electrodes 53a, 53b, 53c, 53d are disposed around the core-shaped conductor 57, thereby forming a plurality of passages of the noise current refluxed from the power line to the ground.
