LPX391M250C3P3

Aluminum electrolytic capacitors are used for storing electric energy and are widely used in the electronics industry. LPX391M250C3P3 belongs to this type of capacitor, specifically a solid aluminum electrochemical capacitor. It is trusted by many users for its long life, low cost and low noise.

The application field of LPX391M250C3P3 capacitor includes regulating the voltage in circuits, other pulse type current circuits and AC/DC conversion circuits. Basically, they provide a filtering effect to dampen electronic noises or transients. They are mainly used in DDR3, DDR4 and GDDR5 applications. They are excellent in low ESR operation and frequency stability, and low impedance is one of their main advantages.

The LPX391M250C3P3’s working principle depends on the electrochemical processes that take place inside the capacitor. While an electrolytic capacitor construction is similar to an ordinary capacitor, it has the additional feature of one of its plates being treated with an etched layer of oxide, which increases the surface area of that plate, allowing the capacitor to store a large amount of charge. This electrode is the negative one, and it is in direct contact with the electrolyte.

When charge is applied to LPX391M250C3P3 capacitor, a very thin layer of oxide is formed on the positive plate, which changes the capacitance value of the capacitor. This oxide layer is very important for the capacitor as it is what makes the capacitor an electrolytic one. The oxide layer also acts as a dielectric, which is why this type of capacitor is able to store a much higher charge than ordinary capacitors.

LPX391M250C3P3 aluminum electrolytic capacitor has a great advantage of long life. The main reason a capacitor has a long life is due to the cathodic protection that the electrolyte provides, which shields the negative plate from corrosion and extends the life of the capacitor.

In summary, LPX391M250C3P3 is an important aluminum electrolytic capacitor for the electronics industry. It is found in many applications, providing voltage regulation, pulse current filtering, and AC/DC conversion, as well as having a long life and low cost. The working principle is based on the electrochemical process that gives it the ability to store a large amount of charge.
