Multilayer Ceramic Capacitors

Abstract

A multi-layer ceramic capacitor is characterized in that rectangular notches are formed in first inner electrode layers and second inner electrode layers, so that when the first inner electrode layers and the second inner electrode layers produce relative position deviation in a length direction of a multi-layer main body, the directly facing area variation of the first inner electrode layers and the second inner electrode layers is small and even is kept unchanged in presence of first rectangular notches and fourth rectangular notches; when the first inner electrode layers and the second inner electrode layers produce relative position deviation in a width direction of the multi-layer main body, the directly facing area variation is small and even is kept unchanged in presence of second rectangular notches, third rectangular notches, sixth rectangular notches, fifth rectangular notches and seventh rectangular notches; or when the first inner electrode layers and the second inner electrode layers produce deviation in the length direction and the width direction simultaneously, the directly facing area variation is small based on the same principle. Therefore, the capacity concentration ratio of the multi-layer ceramic capacitor can be increased, and the qualified rate of finished product is increased.

Description

technical field [0001] The invention relates to electronic components, in particular to a multilayer ceramic capacitor with high capacity concentration. Background technique [0002] The multilayer ceramic capacitor includes a cuboid ceramic body and two external electrodes arranged at opposite ends of the ceramic body. The ceramic body includes a plurality of internal electrode layers stacked alternately and respectively connected to external electrodes of different polarities, and a plurality of dielectric layers respectively stacked between the internal electrode layers of different polarities. The shape of the internal electrode layer is generally rectangular, and adjacent internal electrode layers form a certain facing area to generate capacity. The larger the facing area of ​​adjacent internal electrode layers, the larger the capacity of the multilayer ceramic capacitor. In the manufacturing process of multilayer ceramic capacitors, due to the lamination alignment ac...

AI Technical Summary

Problems solved by technology

In the manufacturing process of multilayer ceramic capacitors, due to the lamination alignment accuracy and other reasons, the relative position between adjacent internal electrode layers will inevitably shift, resulting in a change in the facing area of ​​adjacent internal electrode layers. Changes, leading to poor capacity concentration of multilayer ceramic capacitors
