22UF 400V Aluminum Electrolytic Polar Capacitor In Pakistan

An aluminum electrolytic capacitor, often only called an electrolytic capacitor, uses aluminum metal as one electrode, is covered with a very thin layer of aluminum oxide as dielectric, and has an electrolyte as its second electrode. Aluminum electrolytic capacitors are typically used in power supplies and DC-DC converters for smoothing and buffering rectified DC voltages in many electronic devices.
