摘要： 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.
摘要翻译：提供了能够有效地防止在简单结构中发生颤动噪音的层叠电容器。在层叠电容器中，金属端子围绕电容器元件本体设置。即使当在施加电压时在多层电容器中产生电致伸缩振动时，将金属端子中的基板连接表面和端子连接表面接合在一起的接合表面也可以弯曲，以减轻电致伸缩振动，从而防止发生振动噪声。在层叠电容器中，端子连接面和接头表面形成高度为电容器元件主体的大约一半的上升部分。因此，接合面将位于电容器元件主体的不同侧面的端子连接面和基板连接面连接在一起，从而可以在接合面中确保足够的长度，从而提高减轻电致伸缩振动的效率。此外，将电容器元件主体的底面刚好安装到电容器元件主体支撑表面的前侧上的简单过程可以容易地将金属端子附接到电容器元件主体。
