This application note explains how to measure the characteristics of a capacitor with the impedance adapter B-WIC and the Bode 100.
The ESR of a capacitor can influence the behavior of an electronic system and therefore has to be known in several cases. Manufacturers do often not provide sufficient data about the ESR. Sometimes the dissipation factor is defined at a single frequency. Assuming a series equivalent circuit model for a capacitor including the capacitance and the series resistance, the Bode 100 can directly measure both values over the full frequency range.
