  • Capacitor having a dielectric ceramic layer
    Patent number: 7224573
    Abstract: A capacitor includes at least two pairs of opposing electrode layers and an intermediate dielectric layer. The intermediate dielectric layer includes a ceramic material that contains at least two different components existing in separate phases. The at least two different components have a perovskite structure that contains silver in A-positions and niobium and tantalum in B-positions. A composition of a first component and a composition of a second component are such that temperature coefficients of respective permittivities Tk?A and Tk?B have different signs within a temperature range.
