  • Patent number: 10242803
    Abstract: Methods and systems to improve a multilayer ceramic capacitor using additive manufacturing are disclosed. Conductive layer ends and dielectric layer edges of a multilayer ceramic capacitor may be modified to comprise a round shape, which may increase voltage limits by reducing electric field intensity that results from sharp corners. Further, the capacitor may comprise wave-like structures to increase surface area of a conductive layer and/or dielectric layer. The round shape of the conductive layer end may in-part reduce the need for a wide protective gap due to its dome-shape permitting the dielectric layer to be wider on top and bottom, and thinner at the center, e.g. concave, which provides strength support to the layers. The 3D Printing process permits the distance between the conductive layer end of the conductive layer to be much closer to the dielectric layer edge of the dielectric layer, such as below the standard 500 microns.

  • Patent number: 10236123
    Abstract: Methods and systems to improve a multilayer ceramic capacitor using additive manufacturing are disclosed. Conductive layer ends of a multilayer ceramic capacitor may be modified to comprise a round shape, which may increase structural stability of the capacitor's layers. Other configurations may be possible, such as bulbous or wavy shaped conductive layer ends. The layers may comprise one or more pillars made from dielectric material, e.g., barium titanate, disposed through a portion of a conductive layer. The dielectric material may be the same material used in the insulator layers of the capacitor. Each pillar may comprise a plurality of spot connections surrounding its perimeter. The embedded pillars may be used to prevent delamination of the layers and to increase mechanical strength. Additionally, an algorithm of a computing device may determine an optimal shape, size, and/or configuration of the capacitor based on one or more predetermined specifications or properties.

  • Patent number: 10224151
    Abstract: A capacitor assembly that is capable of performing under extreme conditions, such as at high temperatures and/or high voltages, is provided. The ability to perform at high temperature is achieved in part by enclosing and hermetically sealing the capacitor element within a housing in the presence of a gaseous atmosphere that contains an inert gas, thereby limiting the amount of oxygen and moisture supplied to the solid electrolyte of the capacitor element. Furthermore, the present inventors have also discovered that the ability to perform at high voltages can be achieved through a unique and controlled combination of features relating to the formation of the anode, dielectric, and solid electrolyte. For example, the solid electrolyte is formed from a combination of a conductive polymer and a hydroxy-functional nonionic polymer.
