The impedance of an aluminum electrolytic capacitor is dependent on frequency and temperature. It comprises capacitive reactance of the capacitor, ohmic and dielectric losses of the foils, electrolyte, and terminals, and inductive reactance of the capacitor windings.
Capacitive reactance is the opposition that a capacitor offers to alternating current due to its phase-shifted storage and release of energy in its electric field. Reactance is symbolized by the capital letter “X” and is measured in ohms just like resistance (R). Capacitive reactance decreases with increasing frequency.
Anyone with access to an impedance meter (HP / Venable) can easily tell you that electrolytic capacitors certainly do become inductive at high frequencies. This is part of the reason why you see a lot of ceramic capacitors used in high-frequency DC-DC converters - electrolytics simply aren't that good up in the hundreds of kilohertz / megahertz.
(Inductive & Capacitive) Reactance Definition: Reactance is defined as the opposition to current flow in a circuit element due to inductance and capacitance. Inductive Reactance: Inductive reactance, caused by inductors, stores energy in a magnetic field and makes current lag behind voltage.
An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
Capacitive reactance (in ohms) decreases with increasing AC frequency. Conversely, inductive reactance (in ohms) increases with increasing AC frequency. Inductors oppose faster changing currents by producing greater voltage drops; capacitors oppose faster changing voltage drops by allowing greater currents.
