Summary:This article explains the adaptation of a dipole polarization model to describe the DC voltage and frequency dependence of MLCCs. To demonstrate the practical suitability of the model, it will be tested using measurements on selected MLCCs from Wüirth Elektronik's portfolio. The number of fitting parameters is reduced, allowing an efficient fitting of an extensive capacitor portfolio. The model is developed for implementation in simulating software such as Spice.
