An electrolytic capacitor is a type of capacitor that uses an ionic conducting liquid as one of its plates with a larger capacitance per unit volume than other types. They are often referred to in electronics usage simply as "electrolytics". They are valuable in relatively high-current and low-frequency electrical circuits. This is especially the case in power-supply filters, where they store charge needed to moderate output voltage and current fluctuations in rectifier output. They are also widely used as coupling capacitors in circuits where AC should be conducted but DC should not. Electrolytic capacitors can have a very high capacitance, allowing filters made with them to have very low corner frequencies. B2BManufactures.
