180uF 420V Electrolytic Capacitor 22x30mm
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, which acts as the cathode or negative plate of the capacitor. Due to the very thin dielectric oxide layer and the enlarged anode surface, electrolytic capacitors have a much higher capacitance voltage (CV) product per unit volume than ceramic capacitors or film capacitors and can therefore have large capacitance values.
There are many applications that do not require tight tolerances and AC polarization, but do require large capacitance values. They are often used as filtering devices in various power supplies to reduce voltage ripple. When used in switching power supplies, they are often critical components that limit the usable life of the power supply, so high-quality capacitors are used in this application.
