Background: Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (or AECs) are some of the most widely used capacitors in the industry. An aluminum electrolytic capacitor is a polarized capacitor formed using an aluminum oxide dielectric layer and two conductive (electrolytic) layers of aluminum, allowing it to store a large amount of energy in a small package.AECs are usually divided into two categories- low impedance (low ESR, ESL and ESR) capacitors and high impedance (high ESR, ESL and ESR) capacitors. Low ESR capacitors are widely used for general-purpose applications in power supplies and in motor controllers. High ESR capacitors are mainly used for high-power applications such as energy storage, power switching, switching regulators and DC-DC converters, as well as high-performance audio applications.

EKXJ201ELL121ML20S Application Field and Working Principle

The EKXJ201ELL121ML20S aluminum electrolytic capacitor is a general-purpose device designed to provide reliable performance in a wide range of applications. The capacitor has a capacitance of 2.1µF and a low-impedance design, making it suitable for use in power supplies, motor controllers, as well as switching regulators and DC-DC converters.The working principle of the EKXJ201ELL121ML20S aluminum electrolytic capacitor is simple. Its two conductive layers are made of aluminum, with one layer known as the anode and the other the cathode. The oxide dielectric is applied between the two layers to form an effective barrier. This allows the capacitor to store charge in the form of an electrostatic field. When this charge is discharged through the capacitor, a current flows through the two layers and the dielectric.The combination of the electrolytic layers, dielectric and size allows the capacitor to provide reliable performance in a variety of applications. Its low ESR and high ripple current capability make it suitable for demanding applications such as power supplies, motor controllers and switching regulators. Additionally, its low ESL and low ESR also make it ideal for high-performance audio applications.The EKXJ201ELL121ML20S aluminum electrolytic capacitor is a robust, reliable and cost-effective device designed to provide superior performance and long-term reliability in demanding applications. It is an efficient and reliable choice for power supplies, motor controllers and high-end audio applications.
