Abstract

The electrical properties were investigated to understand better the non-linear behavior of multilayer ceramic capacitors (MLCCs). The electrical properties of the capacitors with a new equivalent circuit were simulated by a Sawyer-Tower circuit system under a high AC-field using B 2 spice software, the simulated results were then compared with the experimental results. The experimental Q-V curves showed the non-linearity of ferroelectricity in the applied AC-fields. The predicted Q-V curves using B 2 spice software under various AC-fields also showed the non-linearity of ferroelectricity in high AC-fields. As a result, the nonlinear dielectricity of the MLCCs was successfully simulated by the new circuit model.
