Multilayer ceramic capacitor based on barium titanate or barium calcium titanate |
摘要 |
A multilayer ceramic capacitor 1 having dielectric layers 2 having barium titanate or barium calcium titanate as a main ingredient. When the dielectric layers are barium titanate, the ratio of the grains having a thickness of the crystal grain boundaries 22 present between adjoining dielectric grains 20 is 30% to 95% of the plurality of dielectric grains 20 forming the dielectric layers 2. When the dielectric layers 2 are barium calcium titanate, the ratio of the grains having a thickness of the crystal grain boundaries 22 present between adjoining dielectric grains 20 is 20% to 70% of the plurality of dielectric grains 20 forming the dielectric layers 2.
