MULTILAYER CERAMIC CAPACITOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18411092 titled 'MULTILAYER CERAMIC CAPACITOR

The patent application describes a multilayer ceramic capacitor with a unique internal electrode configuration.

The multilayer ceramic capacitor consists of a multilayer body with dielectric and electrode layers, as well as external electrodes on its end surfaces.
In the middle portion of the capacitor, the internal electrode layers have end portions that are curved towards a second main surface.
Approximately 90% or more of the internal electrode layers in the width direction exhibit this curved configuration.

Potential Applications: - This technology can be used in various electronic devices that require capacitors for energy storage and signal filtering.

Problems Solved: - The curved internal electrode configuration helps improve the performance and efficiency of the multilayer ceramic capacitor.

Benefits: - Enhanced capacitance and electrical properties. - Improved reliability and longevity of electronic devices.

Original Abstract Submitted

A multilayer ceramic capacitor includes a multilayer body including dielectric layers and electrode layers laminated therein, and two external electrodes respectively provided on two end surfaces of the multilayer body. As seen in a plane including a width and a lamination direction in a middle portion in a length direction, among the internal electrode layers, end portions in the width direction of about 90% or more of internal electrode layers in a middle in the lamination direction are curved toward a second main surface.
