In a multilayer capacitor, a first dielectric layered product including a first body principal face is formed to be thicker than a second dielectric layered product including a second body principal face in a stacking direction thereof. A first external electrode and a second external electrode extend only to the first body principal face from a first body end face and a second body end face. Alternatively, the first external electrode and the second external electrode extend at least to the first body principal face from the first body end face and the second body end face and extend also to at least one of the second body principal face, a first body lateral face, and a second body lateral face.

A multilayer capacitor is provided with improved reliability and reduced 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.

摘要:
A multilayer capacitor is provided which can efficiently prevent chattering noises from occurring in a simple structure.In the multilayer capacitor, a metal terminal is disposed about a capacitor element body. Even when an electrostrictive vibration is generated in the multilayer capacitor upon voltage application, a joint surface joining a substrate connecting surface and a terminal connecting surface together in the metal terminal can flex, so as to mitigate the electrostrictive vibration, thereby preventing chattering noises from occurring. In the multilayer capacitor, the terminal connecting surface and joint surface form a rising part having a height which is about half that of the capacitor element body. Therefore, the joint surface joins together the terminal connecting surface and substrate connecting surface that are positioned on different side faces of the capacitor element body, whereby a sufficient length can be secured in the joint surface, thus improving the efficiency of mitigating electrostrictive vibrations. Further, a simple procedure of just mounting the bottom face of the capacitor element body onto the front side of the capacitor element body supporting surface can easily attach the metal terminal to the capacitor element body.
