Capacitive and inductive regions of capacitance

The low frequency range is very close to the ideal capacitor, and the impedance is inversely proportional to the frequency, and this region is called the capacitive region. With the change of frequency, the impedance tends to increase, and the parasitic inductance effect of the capacitor is very obvious, and this region is called the inductive region.

ESR and ESL of Capacitance:

Figure 1: Circuit equivalence model of capacitance

ESR is the abbreviation of Equivalent Series Resistance, which translates to the equivalent series resistance, and the ESR of the capacitor is the equivalent series resistance of the capacitor.

ESL is the abbreviation of Equivalent Series Inductance, which translates to equivalent series inductance, and the ESL of capacitor is the equivalent inductance of capacitor series series.
