Aluminum Electrolytic Capacitors are amongst the most important components of today’s electrical circuits and devices. Their purpose is to store electrical charge and the ability to release this stored charge quickly and efficiently over a short period of time. The LGU1V153MELB is one such device that is well suited for medium power applications. Its construction, purpose and working principles are explored in this article.

Construction

The LGU1V153MELB is constructed with two aluminum electrodes which are separated by a dielectric layer. The outer aluminum electrode is called the anode while the inner aluminum electrode is called the cathode. These electrodes are then encapsulated in a plastic case which provides protection from mechanical damage and increases the life of the device. At the anode there is an external terminal for connecting the capacitor to the circuit. Inside the device there are two electrolytic solutions, one at the anode and the other at the cathode. These solutions help improve the performance of the capacitor.

Application Field

The LGU1V153MELB is typically used in medium power applications such as in switching power supplies, motor control systems, power DCDC converters and automotive applications. Its large capacity and low leakage current make it well suited for these applications. In addition, its high temperature capability and stable operation within a wide range of temperatures make it an attractive choice for many applications.

Working Principle

When an electric current passes through the device, it attracts the negative charges in the anode electrolytic solution and repels the positive charges in the cathode electrolytic solution. This creates a potential difference between the two electrodes. The potential difference in turn causes a buildup of electric charges on the electrodes which is what allows the device to store electrical charge. The capacitor can be discharged when the current is turned off. This quickly and efficiently releases the stored charge slowly.When a voltage is applied across the terminals, the electric field from the voltage causes a displacement current to flow through the electrolytic solution. This current helps reverse the electrostatic effect of the previous charging process and thus helps the capacitor to further increase its charge storage capacity.The LGU1V153MELB also utilizes its high temperature capability to reduce the formation of surface corrosion and further increase its longevity and stable operation. By maintaining low temperatures, it helps ensure the reliability of the capacitor.

Conclusion

The LGU1V153MELB is an excellent choice for medium power applications due to its high capacity, low leakage current and high temperature tolerance. Its construction and working principle make it a stable and reliable device which helps improve the performance of any circuit or device in which it is used. It is an excellent choice for those looking for a cost effective and reliable capacitor for their projects.
