    摘要： A multilayer ceramic capacitor includes a multilayer body including internal electrode layers and dielectric layers alternately laminated therein, and external electrodes respectively on end surfaces in a length direction intersecting a lamination direction in the multilayer body, and being electrically connected to the internal electrode layers. The internal electrode layers each include an opposing portion and an extension portion. The opposing portion of one internal electrode layer is opposed to an opposing portion of another internal electrode layer adjacent in the lamination direction. The extension portion extends from the opposing portion and is connected to one of the external electrodes in the length direction. The dielectric layers each have a thickness of about 0.3 μm or more and about 0.5 μm or less, and the internal electrode layers include short-circuit prevention internal electrode layers each including a thin portion with a thickness is no more than about 1/20 the thickness of the dielectric layer in the opposing portion.

    摘要： An electronic component device includes an electronic component, a pair of metal terminals, a bonding member, and an expansion member having thermal expansibility. The electronic component includes an element body and a pair of external electrodes. The element body has a pair of end faces opposed to each other. The pair of external electrodes is disposed on the pair of end faces. The pair of metal terminals is electrically connected to the pair of external electrodes. The bonding member bonds one of the pair of external electrodes to one of the pair of metal terminals. The bonding member electrically connects the one of the pair of external electrodes to the one of the pair of metal terminals. The one of the pair of metal terminals includes an opposing face. The opposing face is a flat face.

    摘要： This application describes methods and apparatus for the safety and protection of capacitor units suitable for medium and high voltage applications, for instance within switching modules (400) of a voltage source converter as may be used for HVDC or FACTs. The capacitor unit (300) has a housing (201) within which is a capacitor comprising a plastic film dielectric material, for instance a winding (100) of first and second plastic films (101, 102) with metal coatings (103, 104). A pressure sensor (302) is configured to detect if the pressure in the housing exceeds a first pressure level and a pressure relief valve (304) is configured to vent gas from the housing if the pressure in the housing exceeds a second pressure level which is higher than the first pressure level.

    摘要： A capacitor insulation system is disclosed in the present application. The insulation system includes a dielectric fluid containing a first voltage stabilizing additive of a first concentration. The insulation system further includes a dielectric film containing the first voltage stabilizing additive of a second concentration and impregnated in the dielectric fluid. The first concentration is greater than the second concentration. The insulation system prepared according to the present disclosure can provide an increased and quite stable dielectric strength.

    摘要： A capacitor includes a capacitor element group, a first bus bar, a second bus bar, a case, a filling resin, and a temperature detection element. The capacitor element group includes a plurality of capacitor elements. The first and second bus bars are connected to electrodes of the plurality of capacitor elements. The case accommodates a capacitor unit in which the capacitor element group is connected to the first and second bus bars. The case is filled with the filling resin, and the filling resin is cured in the case. The first bus bar includes a contact region that is in contact with at least one capacitor element in the plurality of capacitor elements at a side close to an aperture of the case, the at least one capacitor element being positioned at a center of the capacitor element group. The temperature detection element is disposed on the contact region.
