Patent ID: 8592334

Claim:
A dielectric ceramic composition comprising: a main component including barium titanate; a first subcomponent including MgO; a second subcomponent including sintering aids of (Ba, Ca) x SiO 2+x , where x is from 0.8 to 1.2; a third subcomponent including V 2 O 5 ; a fourth A subcomponent including R A oxide, where R A is at least one selected from Tb and Dy; a fourth B subcomponent including R B oxide, where R B is at least one selected from Ho, Y, and Yb; and a fifth subcomponent including MnO, wherein: a ratio of the respective subcomponents to 100 mol of said main component is: the first subcomponent: 2.2 to 2.8 mol, the second subcomponent: 2.4 to 2.55 mol, the third subcomponent: 0.05 to 0.10 mol, the fourth A subcomponent: 2.3 to 2.8 mol, the fourth B subcomponent: 0.05 to 0.5 mol, and the fifth subcomponent: 0.1 to 0.4 mol, the mol ratio of said R A oxide to R B oxide is shown by R A /R B , R A /R B is 5.8 to 56, and an average crystal particle size after firing is 0.1 to 0.2 μm.
