Working Principle

The LQS2W181MELZ45 consists of two aluminum stabilizers, an electrolyte and a separator. When an electrical charge is applied to the electrodes of the capacitor, an electric field is created across the separator, which attracts the movement of the electrolyte ions. This causes charge to accumulate on the electrodes, resulting in an increase in the capacitance of the capacitor.

The dielectric layer between the two aluminum stabilizers is made up of a polarizable material, such as an oxide, which has a high breakdown voltage. In other words, this dielectric absorbs the electric charge and stores it, allowing the capacitor to maintain a high capacitance over time.

The electrolyte used in the construction of the LQS2W181MELZ45 capacitor is an aqueous solution of aluminum ions, which increases the density of the charge stored in its dielectric layer. This ensures that the polarization of the capacitor is stable and consistent over time, reducing its leakage current and improving its life span.

In conclusion, the LQS2W181MELZ45 is an aluminum electrolytic capacitor with a wide range of applications in consumer and industrial electronics. Its small form factor allows for increased efficiency and power savings in applications such as audio circuits, automotive, and power supply filters. Furthermore, its ability to efficiently store energy makes it a great choice for energy storage and power electronics in solar and wind energy systems.
