摘要
As a result of investigating the relationship between the dielectric properties of BaTiO3-based dielectrics and the microphonics of multilayer ceramic capacitors (MLCCs), it was confirmed that microphonics, electric-induced strain, and polarization have very high correlation, and piezostriction becomes dominant in electric-induced strain when high DC bias is applied to BaTiO3-based dielectrics in spite of their Very low spontaneous polarizations. Dielectrics with a large paraelectric phase area in which rare-earth elements have diffused into BaTiO3 are useful for applications of MLCCs, especially under high DC bias.
