Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are widely used in the power industry. The EET-HC2W121JA is one of the most popular aluminum electrolytic capacitors in the power industry. It is suitable for high-temperature power transmissions, motor drives, energy conversion and control, aircraft and automotive electronics, and other high-performance applications.

The EET-HC2W121JA has a very wide application field and working temperatures range from -55°C to +105°C. It is a high voltage capacitor, with a voltage rating of up to 400V, and is commonly used in high voltage power supplies. It has an insulation dielectric, making it suitable for use in wet environments. It has the ability to withstand overvoltage and overcurrent, and has a long life cycle and superior reliability in critical applications.

The construction of the EET-HC2W121JA is composed of an aluminum hermetic can with two open stannous-plated end-plates, each of which has a through-hole to allow for electrical connection. Inside the can is a liquid electrolyte which acts as the dielectric material. The aluminum can is filled with an aqueous electrolyte, such as potassium hydroxide, sodium hydroxide, or ammonium hydroxide. A thin layer of activated carbon is then placed at the bottom of the can, and between the end plates and electrolyte, along with a layer of diaphragms and guard rings to prevent the plates from short circuiting. Each of the end plates has a polarized section, which allows a voltage differential between them when the capacitor is connected in an electrical circuit.

The main working principle of the EET-HC2W121JA is capacitance. The aluminum end plates act as the plates of the capacitor, and when a voltage is applied across them, an equal and opposite charge is generated on each plate. This charge is stored in the form of an electric field, with the aluminum plates acting as the dielectric material to create the capacitance. The activated carbon helps to prevent the charge leakage and reduce the electrolytic losses.

The EET-HC2W121JA has high reliability with a long service life and consistent performance under various environmental conditions. It is also able to withstand high current surges as well as extreme temperatures and other demanding conditions. In addition, it has the ability to exhibit very high capacitance values in a small package, making it useful for high power applications.

Overall, the EET-HC2W121JA is an excellent choice for high-temperature power transmission and motor drive applications, energy conversion and control, aircraft and automotive electronics, and other high-performance applications. Its wide working temperature range, high voltage rating, good insulation, and long life cycle make it ideal for a number of industrial applications.
