220uF 25V Electrolytic Capacitor – Keltron

An electrolytic capacitor is a type of capacitor that uses an electrolyte to achieve a much higher capacitance compared to other capacitor types. It is a polarized component, meaning it has distinct positive and negative terminals. The anode (positive plate) is made of a metal that develops a thin insulating oxide layer, which serves as the dielectric. The cathode (negative plate) consists of a solid, liquid, or gel electrolyte that works together with the oxide layer to enable the capacitor’s operation.
