摘要： A three-terminal capacitor includes a main body having a cylindrical or substantially cylindrical shape extending in a first direction and including first and second inner electrodes alternately laminated together with dielectric layers interposed therebetween, a pair of first outer electrodes on two end surfaces of the main body in the first direction and electrically connected to the first inner electrodes, and a second outer electrode electrically connected to the second inner electrodes. The main body includes a projecting portion projecting in a direction perpendicular or substantially perpendicular to the first direction at a position between the pair of first outer electrodes. The second outer electrode is provided on one surface of the projecting portion viewable when viewed in the first direction.

摘要： An electronic component includes an electronic element and an interposer board. The electronic element includes a multilayer body and external electrodes at multilayer body end surfaces and connected to internal electrode layers. The interposer board includes board end surfaces, board side surfaces orthogonal to the board end surfaces, and board main surfaces orthogonal to the board end surfaces and the board side surfaces. One of the board main surfaces is in a vicinity of the electronic element and is joined with one of the multilayer body main surfaces in a vicinity of the interposer board. The interposer board is an alumina board. A maximum length of the interposer board is smaller than a length of the electronic element. A width of the interposer board is smaller than a width of the electronic element.

摘要： A multilayer ceramic capacitor includes a capacitor main body including a multilayer body including dielectric layers and internal electrode layers alternately laminated therein, and external electrodes each at one of two end surfaces of the multilayer body and connected to the internal electrode layers, and two interposers on a surface of the capacitor main body, and opposed and spaced apart from each other. The two interposers include a nickel-plated layer and a tin-plated layer on an outer periphery thereof. The two interposers each include a non-plated region without the nickel-plated layer on an end surface at which the two interposers face each other.

摘要： A multilayer ceramic capacitor includes a laminate including a dielectric ceramic layer and first and second internal electrode layers laminated in a lamination direction, and first and second external electrode connected to the internal electrode layers. The laminate includes a central layer portion, a peripheral layer portion sandwiching the central layer portion, and a side margin sandwiching the central layer portion and the peripheral layer portion. The side margin including an inner layer and an outer layer. In a cross section including a lamination direction and a width direction obtained by cutting the laminate at a central portion in a length direction, Si is segregated in an inner region including the inner layer and a boundary between the inner layer and the central layer portion, and a Si segregation spot in the inner region has a larger area than a Si segregation spot in the outer layer.
