This document summarizes the results of a device modeling report for a ceramic capacitor with part number ECKTBC222ME made by Panasonic. The report details simulation and measurement of the capacitor's equivalent circuit model over a frequency range of 100Hz to 100MHz. Graphs show the frequency response of the capacitor's impedance and phase, with the simulation results matching well with measurements except at the highest frequencies. Key specifications like the frequency at maximum impedance and its impedance value are reported.
