Applications

The LGX2E391MELZ35 is a versatile capacitor which is suitable for use in a variety of applications. It is commonly used in mobile phones and other portable electronics for filtering and decoupling. It can also be used for power supplies and converters, as well as for energy storage. The combination of its high capacitance, low ESR, and stable temperature ratings make it an ideal solution for high-current applications.

Working Principle

Aluminum electrolytic capacitors rely on an electrochemical reaction that occurs between two metal plates and electrolytes. One of the two metal plates is made of aluminum, while the other is made of a material called a cathode. The two metal plates are separated by a layer of an electrolyte, which is a conductive liquid. When current passes through the capacitor, charge is stored on the exposed aluminum plate.

The capacitance of an aluminum electrolytic capacitor is directly related to the distance between the two plates, as well as the surface area of the exposed aluminum plate. Therefore, increasing the plate distance, or decreasing the plate area, will result in a lower capacitance. This is why electrolytic capacitors are considered to be ‘variable capacitors’ that can easily be adjusted to suit the required application.

Conclusion

The LGX2E391MELZ35 is a high-quality, aluminum electrolytic capacitor which is suitable for use in a variety of applications. Its low ESR and high capacitance make it ideal for high-current applications, while its base metal electrode and environmentally friendly design make it compliant with RoHS and other regulations. Its working principle relies on an electrochemical reaction between two metal plates and electrolytes which allows for a fixed electrical charge to be applied at a given voltage.
