Aluminum electrolytic capacitors are electrical devices which rely on electrolysis between two metallic electrical contacts enclosed in a liquid or gaseous electrically-conductive medium. These capacitors are used predominantly in power electronics applications, such as power supplies, motor controls, and switchgear. The EEU-FC1J820B aluminum electrolytic capacitor is a long-life, radial-lead style capacitor that is designed for use in high frequency and medium voltage power supplies. It is a non-polarized capacitor with a rated voltage of 400V.

The EEU-FC1J820B is suitable for a variety of applications in sectors such as industrial automation, automotive, communications, medical, and consumer electronics. It features a high ripple current, low impedance, and a long life prediction ensuring a truly reliable and safe performance. Its use in power supplies enables high-speed switching, as it offers improved noise reduction, stable voltage output, higher power efficiency, and suppresses spike noise.

The aluminum electrolytic capacitor consists of two metal plates, one of which is coated with an oxide film. This thin metal oxide layer serves as the dielectric material and provides electrical insulation between the two metal plates. The two metal plates form the capacitor’s positive and negative terminals. A liquid or gel electrolyte is used to fill the space between the two metal plates, which helps to maintain the capacitance value. The interior of an aluminum electrolytic capacitor is filled with an ionized electrolyte.

The EEU-FC1J820B aluminum electrolytic capacitor has a very specific design in order to maximize its effectiveness. Its anodized SEF electrolyte is highly stable and has a very low ESR, allowing for better ripple current ratings and an extended life prediction. This capacitor also features a 2-pin lead length of 12.5mm, a 416V vibration resistance rating, and a 560V breakdown voltage rating.

The working principle of an aluminum electrolytic capacitor is fairly simple. When a voltage is applied across the two metal plates, electrons are moved from one plate to the other, due to the electrical charge. This movement of electrons is the basis of electrical current, and is what creates the electrical charge at the capacitor’s terminals. As the voltage is removed, the electrons move back to the original plate, which releases the electrical charge and allows the capacitor to be discharged.

The EEU-FC1J820B aluminum electrolytic capacitor is an important component in various power electronics applications, such as power supplies, motor controls, and switchgear. It provides improved noise reduction, stable voltage output, higher power efficiency, and suppresses spike noise. It is also capable of withstanding high temperatures and humidity levels, making it ideal for a wide range of industrial and consumer electronics applications.
