Of course, an actual capacitor will exhibit a minor amount of loss, so the impedance will not be exactly zero even at the self-resonant frequency. In order to represent this loss, the ESR (Equivalent Series Resistance), which is the amount of resistance, is normally included in capacitor equivalent circuits, as shown in Fig. 7.
The multilayer ceramic capacitor and leaded film capacitor show roughly the same characteristics up to the resonance point, but the self-resonant frequency is higher and |Z| in the inductive region is lower in the multilayer ceramic capacitor. This is because, in leaded film capacitors, the inductance is only as large as that due to the lead wire.
