    Abstract: To improve a mounting reliability while maintaining a thickness of the external electrode at a side face of a multilayer electronic component thin. The multilayer electronic component includes ceramic body in which ceramic layers and an external electrode formed to an end face of the ceramic body. The upper electrode layer includes an element having higher standard electrode potential than Cu. The external electrode includes an external electrode end part and an external electrode extension part which is integrally formed with the external electrode end part. 1.20≤t2/t1≤4.50 is satisfied in which t1 is a total thickness of a thickness of the intermediate electrode layer thickness and t2 is a length from an end of the base electrode layer to an end of the upper electrode layer along the first axis of the external electrode extension part connected by the conductive adhesive.

    Abstract: In a planar view of a ceramic capacitor that has low ESL and is embeddable into a substrate, lengths of first and second external electrodes are L1, lengths from portions of the first and second external electrodes farthest from a capacitor main body to portions closer to the capacitor main body by about 40% of a thickness of the first or second external electrode in a laminating direction are L2, a ratio L2/L1 is about 80% or more and about 90% or less. In the planar view, a length of a third external electrode is L3, a length from a portion of the third external electrode farthest from the capacitor main body to a portion closer to the capacitor main body by about 40% of a thickness of the third external electrode in the laminating direction is L4, a ratio L4/L3 is about 80% or more.

    Abstract: A method for fabricating a magnetic capacitor is provided. A first conducting material is deposited to form a first electrode layer. One or more first ferro-magnetic elements are deposited to form magnetic layer and are aligned and magnetized to produce a magnetic field. An insulating material is deposited to form an insulating layer. A second conducting material is deposited to form a second electrode layer. The one or more ferro-magnetic elements are aligned and magnetized to apply the magnetic field to the insulator layer so that the magnetic field is perpendicular to the first electrode layer and the second electrode layer, and so that the magnetic field is periodic along the length of the insulator layer and results in electric dipoles being formed in the insulator layer when a voltage is applied between the first electrode layer and the second electrode layer.

    Abstract: A multilayer ceramic condenser includes a multilayer main body, a first outer electrode, a second outer electrode, a first side part and a second side part. The multilayer main body has a first side, a second side, a third side and a fourth side. The multilayer main body includes a plurality of inner electrodes and a dielectric layer between the inner electrodes. The dielectric layer is formed by a first ceramic dielectric powder. The first side part and the second side part are formed on the second side and the fourth side of the multilayer main body, and formed by a second ceramic dielectric powder having a smaller particle diameter than the first ceramic dielectric powder. A mean grain size of the first side part or the second side part is similar to or smaller than that of the dielectric layer of the multilayer main body.
