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. Because of their very thin dielectric oxide layer and enlarged an…

Electrolytic capacitors, due to being constructed as a very long plate wound into a coil, have relatively high ESL (equivalent series inductance). So high in fact, that they are completely ineffective as capacitors above 100kHz, or 150kHz for polymer types. Above this frequency, they are basically just resistors that block DC.
