17 · Up to the resonance frequency, the capacitor behaves primarily as a capacitive element, and its impedance decreases. The exact impedance at resonance depends on the ESR. However, beyond the resonance frequency, the impedance characteristic shifts to an inductive behavior. As frequency increases further, impedance rises due to the inductance effect.
