MULTILAYER CAPACITOR AND MOUNTING BOARD OF THE SAME

To provide a multilayer capacitor and a mounting board of the same, in which properties such as moisture resistance, toughness, and hardness and densification of a cover may be secured at a certain level or more.SOLUTION: The present invention provides a multilayer capacitor and a mounting board of the same. The multilayer capacitor includes; a capacitor body including an active region having dielectric layers and internal electrodes alternately stacked therein, and upper and lower covers disposed on upper and lower surfaces of the active region, respectively; and an external electrode disposed on the outside of the capacitor body. In the upper and lower covers, when a portion between a boundary surface of the active region and a boundary surface of the capacitor body is divided into two regions, a first cover region adjacent to the active region of the two regions includes grains having a core-shell structure doped with Sn. The first cover region includes 20% or more of Sn-doped grains of a core-shell structure relative to the total of grains in the first cover region.SELECTED DRAWING: Figure 1 【課題】カバーの緻密度及び耐湿性、靭性、硬度などの特性を一定レベル以上確保することができるようにした、積層型キャパシタ及びその実装基板を提供する。【解決手段】本発明は、交互に積層された誘電体層と内部電極を含む活性領域と上記活性領域の上下面にそれぞれ配置される上部及び下部カバーを含むキャパシタ本体と、上記キャパシタ本体の外側に配置される外部電極と、を含み、上記上部及び下部カバーにおいて、上記活性領域の境界面と上記キャパシタ本体の境界面との間を２つに割る場合、上記２つの領域のうち上記活性領域に隣接した第１カバー領域は、Ｓｎがドープされたコア－シェル構造を有するグレインを含み、上記第１カバー領域は、上記第１カバー領域の全体に対してＳｎがドープされたコア－シェル構造のグレインを２０％以上含む積層型キャパシタ及びその実装基板を提供する。【選択図】図１
