10uF 40V Electrolytic Capacitor – Keltron

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