The paper deals with the EMI filter models for the calculation of the insertion loss characteristics. The insertion loss is in fact the basic EMI filter property. Unfortunately it is not easy to precisely define and measure this parameter through the wide frequency range. The uncertainty of the potential impedance termination really complicates the measurements and also comparison of the performance of filters. The model with the spurious components is introduced in this paper. The procedure of creation of the model is also added up. The spurious components make with the real ones the resonance circuits. The resonance frequencies make the breakages in the insertion loss characteristic. Their resonance frequencies were identified by the analysis of equivalent circuits of the filter for both different measuring systems. The calculation of the values of spurious components, based on knowledge of resonance frequencies, is mentioned at the end of the paper.
