  • Patent number: 7019957
    Abstract: Internal dielectric layers isolated between them by a ceramic layer are arranged in a dielectric body, other internal conductor layers also isolated between them by a ceramic layer are arranged in the dielectric body by being isolated from the above internal conductor layers. Each of the all internal conductor layers is formed with a cut part, and a channel part is formed around the cut part, and the channel parts are arranged so that currents flow in mutually reverse directions between channel parts of internal conductor layers adjoining across a ceramic layer. Consequently, the equivalent serial inductance of the multilayer capacitor is largely reduced and fluctuations of a power source voltage of a CPU is made small.
    Type: Grant
