MULTILAYER CERAMIC CAPACITOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18218303 titled 'MULTILAYER CERAMIC CAPACITOR

Simplified Explanation

The patent application describes a multilayer ceramic capacitor with specific electrode layer configurations.

• The capacitor has a multilayer body with alternating dielectric and internal electrode layers.
• External electrode layers are provided on both end surfaces of the multilayer body.
• The external electrode layers are connected to the internal electrode layers.
• The external electrode layers have a base electrode layer divided into three regions.
• The first region contains a higher amount of metal found in the internal electrode layers.
• The second region contains a higher amount of glass.
• The third region contains a higher amount of copper.

Original Abstract Submitted

A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrode layers alternately laminated therein, and external electrode layers respectively provided on both end surfaces of the multilayer body in a length direction intersecting a lamination direction, and each connected to the internal electrode layers, the external electrode layers each further including a base electrode layer including a first region, a second region, and a third region divided therein, in order from the multilayer body. The first region includes a metal included in the internal electrode layers in a higher amount than the second region and the third region, the second region includes glass in a higher amount than the first region and the third region, and the third region includes copper in a higher amount than the first region and the second region.
