Aluminum Electrolytic Capacitors: ELXS451VSN820MP25S Application Field and Working Principle

Aluminum electrolytic capacitors (AECs) are an integral part of many electrical and electronic circuits, providing a stable, reliable, and low-cost way to temporarily store energy. One type of AEC is the ELXS451VSN820MP25S, a high-performance aluminum electrolytic capacitor developed by Panasonic. This type of AEC is known for its miniature size with a 105°C temperature rating, its long-life performance characteristics, and its low ESR and ESL. It is particularly suited for automotive, industrial, IT, and consumer electronic applications.

Aluminum electrolytic capacitors use a chemical reaction between a conductive oxide layer on an aluminum plate and electrolytes—such as an aqueous solution of potassium hydroxide—to achieve its goal of storing energy. In a nutshell, when a voltage is applied to the positive and negative plates, the electrolytes and the aluminum oxide film act as a barrier, allowing charge to accumulate on the plates and form an electric field that stores energy. The energy stored is dependent on the capacitance value determined by the plate area and the thickness of the oxide film.

The ELXS451VSN820MP25S has a capacitance range of 220 to 220μF and a working voltage of 6.3V to 10V. The product is rated for 1,000 hours of operation at a temperature of 105°C. This AEC also features an additional seal resistant to humidity and vibration, which further safeguards the capacitor’s components and increases its endurance. The low ESR and ESL of the ELXS451VSN820MP25S also make it suitable for use in high-frequency circuits.

Due to its miniature size, the ELXS451V SN820MP25S can be used in a wide range of electronic products with a limited space available. It is widely used in automotive electronics due to its high vibration resistance and its ability to withstand extreme temperature variations. It is also suitable for use in LED drivers, UPS systems, and solar power inverters, as well as consumer electronic products such as digital still and video cameras. It can also be used in IT products such as PCs, laptops, and mainframe computers.

The ELXS451V SN820MP25S aluminum electrolytic capacitor is an ideal choice for applications requiring reliable operation in extreme temperature and vibration environments. Its miniature size and low ESR and ESL make it suitable for a wide range of applications. It is an excellent product for automotive, industrial, IT, and consumer electronic applications, and its small size makes it perfect for installations where space is at a premium.
