Multilayer Ceramic Capacitors

Abstract

A multi-layer ceramic capacitor adopts the structure that a first inner electrode layer and a second inner electrode layer are provided with rectangular notches, so that when the first inner electrode layer and the second inner electrode layer are subjected to relative position deflection in the length direction of a multi-layer main body, owing to existence of both the first rectangular notch and the fourth rectangular notch, the facing area of the first inner electrode layer and the second inner electrode layer is slightly changed or even kept unchanged; when relative position deflection occurs in the width direction of the multi-layer main body, owing to existence of the second rectangular notches, the third rectangular notches and the fifth rectangular notches, the facing area is slightly changed or even kept unchanged; or deflection occurs in both the length direction and the width direction, and according to the same principle, the facing area is slightly changed. Therefore, the volume concentration ratio of the multi-layer ceramic capacitor can be improved, and the end-product qualified rate 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
