    摘要: A multilayer ceramic capacitor having internal electrode layers and dielectric layers with dielectric particles is disclosed. An average particle diameter of the dielectric particles, when measured parallel with the direction of the internal electrode layers, is larger than a thickness of the dielectric layer. A ratio (R/d) between the average particle diameter (R) and the thickness (d) of the dielectric layer is 1

    摘要: The present invention relates to a dielectric ceramic composition comprising BaTiO3, BaZrO3, and the oxide of R wherein, when A is the content of BaZrO3, and C is the content of the oxide R, with respect to 100 moles of BaTiO3, then A is 40≦A≦65 moles and C is 4≦C≦15 moles; plus said dielectric composition satisfies the equation (1) and (2). The present invention can provide a dielectric ceramic composition good in IR lifetime, and capable to be suitably used for medium-high voltage which has a high rated voltage (for example, 100V or more). 0.0038A−0.147≦B≦0.004A+0.04  Equation (1) (note that, B is a ratio of the X-ray diffraction maximum intensity among peaks of said BaZrO3 with respect to the X-ray diffraction maximum intensity among peaks of said BaTiO3). 0.0041C−0.0115≦D≦0.0046C+0.084  Equation (2) (note that, D is a ratio of the X-ray diffraction maximum intensity among peaks of the oxide of said R with respect to the X-ray diffraction maximum intensity among peaks of said BaTiO3).
