2200uF 25V Electrolytic Capacitor – Keltron

An electrolytic capacitor is a capacitor that uses an electrolyte to achieve a much higher capacitance compared to other capacitor types. It is a polarized device, where the anode (positive plate) is made of metal that develops an insulating oxide layer serving as the dielectric. The cathode (negative plate) consists of a solid, liquid, or gel electrolyte that works with the oxide layer to enable charge storage.
