  • Dielectric ceramic composition
    Publication number: 20010022717
    Abstract: A dielectric ceramic composition contains 100% by weight of main component composed of about 35 to 55% by weight of SrTiO3, about 10 to 35% by weight of PbTiO3, about 5 to 12% by weight of CaTiO3, about 8 to 25% by weight of Bi2O3 and about 5 to 13% by weight of TiO2, and about 0.02 to 0.5% by weight of MnO, about 0.05 to 2% by weight of an oxide of at least one element selected from the group consisting of La, Ce, Nd, Pr, Sm, Dy, Er and Y, and about 0.02 to 0.8% by weight of CuO. The dielectric ceramic composition can provide a capacitor which exhibits a low loss and a high dielectric constant, and which can be used in the high frequency region, thereby permitting the advance in miniaturization of the capacitor.
