Aluminum electrolytic capacitors are electrochemical energy storage components that use aluminum oxide as the dielectric material, and are widely used in electronic circuits. ELXS451VSN181MP45S is an aluminum electrolytic capacitor. This article will discuss its application field and working principle respectively.

Application field

ELXS451VSN181MP45S has many application fields. Firstly, since it has a large capacitance and is suitable for high temperature environment, it is used in devices such as power supplies, motors, etc. Secondly, since its rated working voltage is high, it is suitable for entering alternating current (AC) motor, while also available as a snubber and/or filter capacitor in power lines. Moreover, due to its reliable leakage current, it is also suitable for use in various telecom fields.

Working principle

The core of the Aluminum Electrolytic Capacitor is a rolled strip of aluminum foil made of pure aluminum. One side of the aluminum foil has a thin layer of oxygen-free electrolytic partly and the other side is a thin film of metallized (nickel and cobalt) that can prevent corrosion. The two strips of aluminum foil sandwich the electrolyte paper and wound together in a cylindrical shape. The oil-filled electrolyte cells of the capacitor are isolated from the outside world. When a voltage is applied, the negative charge moves to the aluminum surface, forming a thin insulating layer of aluminum oxide. This inversion creates a charge-separating coating on the aluminum that acts as the capacitor\'s dielectric, thus generating the capacitance.

In summary, ELXS451VSN181MP45S aluminum electrolytic capacitor has a large capacitance and is suitable for high temperature environments. It has a high rated working voltage and reliable leakage current, so it is widely used in power supplies, motors, telecommunications and other fields. Its working principle is that an insulating layer of aluminum oxide is formed in the aluminum surface, and it acts as a dielectric to separate the charges and generate capacitance.
