N2 - In this study, vibration of MLCC was analyzed considering nonlinear characteristic of BaTiO3. By construction of FE model of MLCC, total deformation was classified into piezoelectric and electrostrictive deformation. As piezoelectric coefficient is largely influenced by polarization of dipoles, poling process was proceeded to reduce the piezoelectric deformation. 4 variables were considered factors of poling process; heating temperature, poling voltage, dc voltage input time, and aging time. The effects of poling process were verified by experiment and FEA; vibration was reduced by 39.7%. For poled MLCC soldered on simple rectangular circuit board, sound pressure level was reduced by more than 4 times compared to unpoled state.
