Dielectric composition with high-temperature stability

A method for preparing a dielectric composition, the method comprising:

• preparing a barium titanate-based base material major component;
• preparing at least one minor component including, among a first minor component including one or more selected from the group consisting of oxides and carbonates of one or more elements among Yb, Sc, Lu and Tm;
• a second minor component including one or more selected from the group consisting of oxides and carbonates of one or more elements among Dy, Y, Ho, Tb, Gd, Eu and Er;
• a third minor component including one or more selected from the group consisting of oxides including Ba and Zr;
• a fourth minor component including one or more of oxides and carbonates of fixed-valence acceptor element including Mg;
• a fifth minor component including one or more selected from the group consisting of oxides and carbonates of variable-valence acceptor element including one or more of V, Mn, Cr, Fe, Ni, Co, Cu, and Zn;
• and a sixth minor component including one or more selected from the group consisting of oxides, carbonates and glass of Si element, the first minor component, the second minor component and the third minor component;
• preparing a mixture including the base material major component and the at least one minor component;
• and
• calcining the mixture,
• wherein a content of the one or more elements included in the first minor component is 0.2 parts by mole to 6 parts by mole with respect to 100 parts by mole of the base material major component;
• a content of the one or more elements included in the second minor component is 0.2 parts by mole to 6 parts by mole with respect to 100 parts by mole of the base material major component;
• and
• a content of the third minor component is 4 parts by mole to 6 parts by mole with respect to 100 parts by mole of the base material major component.
