摘要： An arrangement and a method for the gradual shutoff of potential in high voltage technology. The arrangement has at least one armature body, an electrically insulating film, and electrically conductive regions. The electrically conductive regions are arranged between layers of the electrically insulating films, and at least parts of the electrically insulating film are arranged around the at least one armature body. The arrangement is used in direct current applications. Resistive compensation currents are reduced and/or avoided along the electrically insulating film, and/or by an armature body, which functions as a first gradual potential shutoff coating, and/or by way of the electrical contacting of the outermost electrically conductive region between layers of electrically insulating film via an electrical contact through an opening in the outer layer of the insulating film.

摘要： A filter device includes an insulator, an inductor, a capacitor, and first and second outer electrodes. In plan view from one major surface, the capacitor overlaps a portion of a conductor pattern in the insulator. The second outer electrode is electrically coupled to the capacitor. The second outer electrode includes side portions on specific opposite side surfaces of the insulator. The capacitor includes a first electrode pattern electrically coupled to the inductor, and a second electrode pattern electrically coupled to the side portions of the second outer electrode with at least one wiring pattern that extends parallel or parallel or substantially parallel to a portion of the conductor pattern.

摘要： An inductor component includes a rectangular parallelepiped element body containing a magnetic material and having a planar main surface, an inductor wiring, and a plurality of columnar wirings. The main surface has a straight side. The inductor wiring includes a pair of pad portions and a wiring main body. The wiring main body has a parallel part extending parallel to the straight side and adjacent to the side without interposing other parts of the inductor wiring therebetween. A dimension in a direction orthogonal to a center line of the wiring main body and parallel to the main surface in the wiring main body is a width dimension, and a shortest distance from the side to the parallel part when viewed through in a direction orthogonal to the main surface is defined as a specific distance. The specific distance is less than the width dimension of the parallel part.
