Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that utilizes aluminum as the anode material which is oxidized to form an insulating layer on its surface. The insulating layer acts as the dielectric material in the capacitor and is key to the capacitor’s ability to store an electrical charge.

The AFC475M50C12B-F is one of the aluminum electrolytic capacitors available. It is a non-polarized, axial lead capacitor specifically designed to meet the requirements of the telecommunications, power supplies and other demanding industrial applications. It is able to store up to 8 times the energy of similarly sized capacitors and is capable of handling high frequency and power ripple currents. It also features low impedance and long life expectancy, making it a popular choice for many applications.

Application Field

The AFC475M50C12B-F aluminum electrolytic capacitor is a durable and reliable capacitor suitable for many different applications. It is used in areas such as switching power supplies, DC/DC converters, LED lighting, motor drives, modulation circuits, power inverters, and solar energy applications. It is also used in a variety of communications systems, such as satellite communications, radio communications, and optical communications, as well as in automotive, aerospace, and military applications.

Working Principle

When an electrical current is applied, ions of the electrolyte move towards the anode polymer layer, thus forming an “ions conductive layer” which is responsible for the conduction of electricity. The ions of the electrolyte react with the aluminum anode forming a thin dielectric layer of aluminum oxide on its surface. As the electrolyte is circulated, the dielectric layer protects the aluminum from further oxidation and keeps the capacitor’s capacitance constant.

The aluminum electrolytic capacitors ability to store an electrical charge is based on the principles of electrostatics. When a voltage is applied to the terminals of the capacitor, an electric field is generated and the electrical charges are stored on the dielectric layer in the form of an electric dipole, allowing the capacitor to store energy. The AFC475M50C12B-F is designed with an electro-chemical design that maximizes capacitance and enables the capacitor to store up to 8 times the energy of similarly sized capacitors.
