摘要： A multi-layer ceramic capacitor includes a multi-layer unit and a side margin. The multi-layer unit includes ceramic layers laminated in a first direction, internal electrodes disposed between the ceramic layers, a main surface oriented in the first direction, a surface layer portion in a range from the main surface to a predetermined depth, and a center portion adjacent to the surface layer portion in the first direction. The side margin covers the multi-layer unit from a second direction orthogonal to the first direction. The ceramic layers have an average dimension in the first direction that is 0.4 μm or less. Each of the internal electrodes includes an oxidized region adjacent to the side margin. The oxidized region in the surface layer portion has a dimension in the second direction that is equal to or more than two times the average dimension of the ceramic layers in the first direction.

摘要： A capacitor assembly for use in, and a method of assembling, a filtered feedthrough. The capacitor includes an insulative member fixedly attached to its bottom portion to inhibit high voltage arcing. The termination material present on the inner and outer diameters of the capacitor is absent from a portion of the capacitor proximate the bottom portion, e.g., at the insulative member.

摘要： In a ceramic electronic component, an electrically conductive resin layer is arranged to cover a thick film layer and to extend beyond the end of the thick film layer by at least about 100 μm and a plating layer is arranged to cover the electrically conductive resin layer except a region having a dimension of at least about 50 μm and extending along the end of the electrically conductive resin layer. Consequently, the concentration of the stress is reduced.

摘要： A method and apparatus is provided that pertains to a low inductance capacitor. The capacitor has a first surface electrically interconnected to a plurality of conductive electrodes and one or more second surfaces electrically interconnected to a plurality of electrodes interposed between the electrodes electrically interconnected to the first conductive surface. A dielectric layer separates the layered plurality of electrodes. The one or more second conductive surfaces are positioned within the body of the layered electrodes, such that the distance between the terminations of the first conductive surface and the one or more second conductive surfaces is shortened to lower inductance.

摘要： A capacitor mounting structure is proposed which can easily relieve a stress given to an extraction lead when ambient temperature is changed, soldering is made, or vibration is given, and can prevent breakage of the extraction lead. An outside holder is provided at an outside of a resin case housing a capacitor covered with a filler, and an inside holder is provided. The outside holder includes an upper outer wall bonded to an upper resin wall of the resin case. Lower openings of the resin case and the outside holder overlap with each other and form a lower space. An extraction lead is disposed in the lower space.
