Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors have become increasingly important electronic components over the years with their excellent electrical characteristics and wide range of applications, from sample and hold circuits used in radio receivers to bridge peak currents required in motors. The EKYA101ELL470MJC5S is a type of aluminum electrolytic capacitor and is a very common choice for many applications across a range of industries. This article aims to illuminate its application field and working principle.

Application Field

The EKYA101ELL470MJC5S is a low impedance, aluminum electrolytic capacitor, designed with a long life, and sealed in a snap-in version of the D-shaped can, with an operating temperature range between -40°C and +85°C. It is also LXW rated, meaning it is suitable for use in applications with switching power supplies, low frequency power supplies, automotive electric circuits and other DC power supply circuits. It is also suitable for applications with high-efficiency power supplies such as LED lighting, motor control circuits, and welding equipment.

With its ability to handle high current, the EKYA101ELL470MJC5S is highly recommended for industrial power supplies, computer motherboards, televisions, and other consumer electronic equipment requiring a high level of energy storage. It is also used in inverters, power factor correction, surge protectors and other applications where the performance of aluminum electrolytic capacitors is important.

Working Principle

The EKYA101ELL470MJC5S is a kind of aluminum electrolytic capacitor which works on the principal of electrolytic conduction. An electrolyte is used as an insulating medium between two metal electrodes and an electrical charge is applied. When the electrical charge passes through the electrolyte, ions transfer between the two metal electrodes. This leads to a voltage drop which results in a capacitance.

The structure of the EKYA101ELL470MJC5S consists of two aluminum sheets, an oxide layer, an electrolyte medium, and two connectors. The aluminum sheets act as two electrodes and the oxide layer is used as an insulator. As the electrical charge is applied, the ions in the electrolyte flow between the two electrodes, thus creating a voltage drop, which results in a capacitance. The size and composition of the capacitor can be adjusted to achieve specific capacitance values.

The EKYA101ELL470MJC5S is a polarized capacitor, meaning the positive and negative terminals must be connected correctly. If they are connected incorrectly, it can lead to an electrical breakdown and the capacitor will be damaged. If the capacitor is installed correctly, it will enable a stable output current and voltage.

Conclusion

The EKYA101ELL470MJC5S is a low impedance, aluminum electrolytic capacitor designed for long life and a wide range of applications. With its ability to handle high current, it is highly recommended for industrial power supplies, computer motherboards, televisions, and other consumer electronic equipment requiring a high level of energy storage. It also works on the principal of electrolytic conduction where an electrical charge passing through the electrolyte results in a voltage drop and thus capacitance. The EKYA101ELL470MJC5S is a polarized capacitor and the positive and negative terminals must be connected correctly to ensure a stable output current and voltage.
