摘要： In a method of calculating effective power relating to a capacitor, the waveform of a periodic voltage applied to a capacitor is set. The capacitance of a desired capacitor is input. The waveform of the periodic voltage applied to both ends of the capacitor is subjected to Fourier expansion. More specifically, the periodic voltage is Fourier-expanded in terms of sine and cosine-wave series of high-order frequency components. Further, an effective power consumed by the capacitor is calculated using data regarding temperature characteristics, voltage characteristics and a frequency characteristic of the capacitance and dielectric tangent of the capacitor.

摘要： A ceramic capacitor comprising a dielectric ceramic element made of materials a metal oxide as the principal ingredient. On the surface of the dielectric ceramic element are formed a plurality of electrodes. The materials used for the electrode are selected such that their principal ingredients have a stronger oxidizing tendency than those used for the dielectric ceramic element. The electrode is formed by applying this electrode material on the surface of the dielectric ceramic element and subsequently baking in a non-reducing atmosphere. This process reduces the surface of the dielectric ceramic element underneath the electrode and a reduced layer is thus formed.
