220uF 200V Electrolytic Capacitor 18x30mm - Short Legs

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 serves as the capacitor's dielectric. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, which serves as the capacitor's cathode, or negative plate. Due to their very thin dielectric oxide layer and enlarged anode surface, electrolytic capacitors have a much higher capacitance-voltage product (CV) per unit volume than ceramic capacitors or film capacitors and can therefore have large capacitance values.
