摘要： In a feed-through capacitor, a conduction unit having a plurality of conduction inner electrodes can fully secure a tolerable level of DC. A capacitor unit is formed on the mount surface side in a capacitor body, so that high-frequency noise components can be removed by the capacitor unit before reaching the conduction unit. The distance between the grounding inner electrode located closest to the conduction unit and the conduction inner electrode in the conduction unit is greater than that between the signal inner electrode and grounding inner electrode in the capacitor unit. This enhances the impedance between the capacitor unit and the conduction unit, so as to inhibit the high-frequency noise components from flowing into the conduction unit.

摘要： Disclosed is a multilayer capacitor capable of improving reliability and further reducing ESL. In a width direction, a second principal-surface electrode portion is greater than a first principal-surface electrode portion, and a fifth principal-surface electrode portion is greater than a fourth principal-surface electrode portion. When viewed from a lamination direction, an outer edge of the second principal-surface electrode portion at the other end side is arranged near the other end side more than outer edge of the fifth principal-surface electrode portion at one end side. First lead portions are connected to the second principal-surface electrode portion, and second lead portions are connected to the fifth principal-surface electrode portion. Thus, portions of the second principal-surface electrode portion greater than the first principal-surface electrode portion and portions of the fifth principal-surface electrode portion greater than the fourth principal-surface electrode portion function as current paths between the first lead portions and the second lead portions. Therefore, the current paths are shortened.
