DIELECTRIC CERAMIC COMPOSITION AND CERAMIC ELECTRONIC COMPONENT COMPRISING THE SAME
PROBLEM TO BE SOLVED: To provide a dielectric ceramic composition that has a high insulation resistance and has a capacity temperature characteristic satisfying the X9R characteristic of the EIA standard.SOLUTION: The dielectric ceramic composition is provided that contains as a main component, barium calcium titanate represented by a composition formula BaCaTiO(x is 0.05 or more and 0.1 or less) and as an accessory component, an oxide of Y and an oxide of Yb. In the dielectric ceramic composition, the content of the Y oxide is 0.5 to 2 mol in terms of YOwith respect to 100 mol of barium calcium titanate, the content of the oxide of Yb is 0.5 to 2 mol in terms of YbOwith respect to 100 mol of barium calcium titanate, and the average particle size is 0.3 μm or more. Further, a dielectric magnetic composition is provided that is identical to the above dielectric magnetic composition except that dielectric magnetic composition is preferably a core-shell structure.SELECTED DRAWING: None
