N2 - Effective piezoelectric coefficient for finite element method of multi-layer ceramic capacitor was calculated in this study considering three factors; reduction ratio of the number of layer in finite element model, electrostriction, and applied DC voltage. Fundamental and second harmonic frequency of vibration response was measured when MLCC is operated under sinusoidal AC voltage and various DC voltage. Vibration measurements were separated into piezoelectric and electro-strictive vibration. Using finite element analysis, piezoelectric and electrostrictive coefficients were calculated and effective piezo-electric coefficients were also calculated.
