An aluminum electrolytic capacitor (also known as an electrolytic capacitor, an aluminum electro or al-electro) is a polarized capacitor that consists of two aluminum foils separated by a film of oxide which acts as the dielectric. The aluminum foils, one known as the anode and the other as the cathode, are etched with a porous surface to act as current collectors, allowing charge carriers to enter and leave the electrodes. As the name suggests, electrolytic capacitors employ an electrolyte to complete the current path.

The 400SAW47MEFCGC18X20 aluminum electrolytic capacitor is a high-performance aluminum electrolytic capacitor, offering high capacitance, low equivalent series resistance, and a wide temperature range for reliable operation in various applications. Its applications include power supply and power filter, acoustic filter, intermittent and voltage stabilization circuits, AC line filters, DC link circuits, high-voltage circuits, motor start circuits, and surge suppressors. This capacitor has a maximum working voltage of 400V and a maximum ripple current of 4.5A.

The working principle of an aluminum electrolytic capacitor is that the metal layer produces a static electricity when metal is placed in an electrolyte solution. The polarized nature of the electrolytes causes the electrolyte to rapidly give and take protons between the metal plates. The resulting flow of electrons through the capacitor creates electrical energy.

The 400SAW47MEFCGC18X20 aluminum electrolytic capacitor features a high surge current capability, wide temperature range, high capacitance, and low equivalent series resistance.
