    摘要： A capacitor packaging having a central termination and three or more capacitors (or groups of capacitors) arranged about the central termination. The electrical flow paths between the termination and the capacitors or groups of capacitors are of substantially the same length. The capacitors or groups of capacitors may be arranged in a generally circular pattern with the termination centered on the center. The termination may include first and second terminals. The capacitors may be mounted to a printed circuit board (“PCB”) with traces on opposite surfaces of the PCB providing electrical flow paths from the terminals to opposite legs of the capacitors. The capacitor packaging may include a primary PCB with a first circular arrangement of capacitors and a secondary PCB with a second circular arrangement of capacitors. The capacitors may be sandwiched between the PCBs with the second arrangement of capacitors disposed concentrically inwardly of the first arrangement.

    摘要： A multilayer capacitor includes: a body including a dielectric layer, and first and second internal electrodes stacked on each other in a thickness direction of the capacitor while being spaced apart from each other with the dielectric layer interposed therebetween; a first external electrode connected to the first internal electrode; and a second external electrode spaced apart from the first external electrode in a length direction of the capacitor that is perpendicular to the thickness direction, and connected to the second internal electrode. One of the first internal electrode and the second internal electrode has a horizontal plane perpendicular to the thickness direction and an inclined plane inclined with respect to the horizontal plane in at least a partial region thereof.

    摘要： A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrode layers that are laminated, first and second main surfaces opposed to each other in a lamination direction, first and second lateral surfaces opposed to each other in a width direction orthogonal or substantially orthogonal to the lamination direction, and first and second end surfaces opposed to each other in a length direction orthogonal or substantially orthogonal to the lamination direction and the width direction. The multilayer body further includes external electrodes that are respectively provided on the first end surface and the second end surface and connected to the internal electrode layers. The internal electrode layers each include first and second regions respectively including different coverages. The first region includes a larger coverage than the second region. The first region is connected to a corresponding one of the external electrodes.
