摘要:
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 TkεA and TkεB have different signs within a temperature range.
