Aluminum Electrolytic Capacitors are widely used in both high-power and high-energy applications, such as capacitive filtering, high frequency transient suppression, reverse bias for discharge protection, decoupling and storage. E81D251VNN391MA30N is a type of aluminum electrolytic capacitor which is designed for use in applications that require long life and improved reliability. This capacitor is extremely resistant to environmental conditions such as humidity, temperature, vibration, and shock.

The construction of aluminum electrolytic capacitors includes a can filled with electrolyte liquid, an anode made of aluminum foil, a dielectric made from insulating paper, a cathode made from aluminum oxide, and a conductive sealant. The Aluminum Electrolytic Capacitors have a higher equivalent series resistance (ESR) than other capacitors, which means they are typically used as DC blocking capacitors. It is also essential to note that the E81D251VNN391MA30N is designed for operating in extremely temperature and voltage environments.

The aluminum electrolytic capacitor consists of two small metal plates (anode and cathode) separated by an electrolyte and an insulating sheet. The electrolyte serves as an ion bridge between the plates and it is what allows current to flow through the capacitor. During the operation of the capacitor, an electric field is created between the plates which stores energy. When the electric field comes into contact with the electrolyte, it generates positive and negative ions which flow between the two plates.

The working principle of E81D251VNN391MA30N aluminum electrolytic capacitor is similar to that of a normal capacitor. It works by transferring energy in the form of electrical charges from one plate to the other using the electrolyte as an ion bridge between the two plates. The capacitor is able to hold a charge due to the electric field created between the two plates. This electric field can be controlled using a voltage regulator, and it is also possible to control the capacitor\'s charge rate and capacitance through the use of a variable voltage source.

The E81D251VNN391MA30N application field is mainly used in applications that require high frequency filtering. This is because the ESR of the capacitor is very low, meaning that it is capable of creating signal frequencies up to 20kHz. It is also ideal for applications such as DC blocking, reverse discharging protection, current-limiting, and pulse-width modulation. It is also suitable for use in high-power electronic equipment.

In conclusion, the E81D251VNN391MA30N aluminum electrolytic capacitor is a type of capacitor designed for use in applications that require long life and improved reliability. This capacitor is extremely resistant to environmental conditions such as humidity, temperature, vibration, and shock. Moreover, the working principle and applications fields of the capacitor are also discussed.
