Dielectric ceramic composition and electronic device

Abstract

A dielectric ceramic composition comprising a main component of BaTiO3, a first subcomponent including at least one compound selected from MgO, CaO, BaO, SrO and Cr2O3, a second subcomponent of (Ba, Ca)xSiO2+x (where, x=0.8 to 1.2), a third subcomponent including at least one compound selected from V2O5, MoO3, and WO3, and a fourth subcomponent including an oxide of R1 (where R1 is at least one element selected from Sc, Er, Tm, Yb, and Lu), a fifth subcomponent including an oxide of R2 (where R2 is at-least one element-selected from Y, Dy, Ho, Tb, Gb and Eu), wherein the ratios of the subcomponents to 100 moles of the main component of BaTiO3 are first subcomponent of 0.1 to 3 moles, second subcomponent of 2 to 10 moles, third subcomponent of 0.01 to 0.5 mole, fourth subcomponent of 0.5 to 7 moles, and fifth subcomponent of 2 to 9 moles (where the number of moles of the fourth and fifth subcomponents are respectively the ratio of R1 and R2 alone).
