Aluminum Electrolytic Capacitors-LGL2G391MELB30 Application Field and Working Principle

The aluminum electrolytic capacitor (AEC) is a type of capacitor that contains an electrolyte developed using aluminum as one of its main components. It is one of the most common types of capacitor due to its moderately high capacitance value, wide operating temperature range, long life span and its relatively low cost for capacitance ratings up to about 3300µF. It is currently used in a variety of applications such as power supplies, audio and data systems and automotive applications.

The LGL2G391MELB30 capacitor is a aluminum electrolytic capacitor with a rated voltage of 16V and a capacitance of 2.2µF. It is a miniature capacitor that offers an excellent way to store and release energy in a variety of circumstances, including power supply applications. Thanks to its low ESR and excellent temperature stability, the LGL2G391MELB30 is a very reliable and robust component.

Working principle of LGL2G391MELB30 Capacitor

The LGL2G391MELB30 capacitor is an electrolytic capacitor that uses a wet electrolyte as the dielectric material between the two electrodes. This dielectric material is formed from an electrolyte solution of aluminum tannin and an electrolyte component, usually potassium hydroxide. The electrodes are made from a strip of foil with an oxide coating, which acts as one of the electrodes. The other electrode is the cathode, which is usually made from an aluminum oxide layer, and is connected to the destination and source of the electric current.

The capacitance of an aluminum electrolytic capacitor is determined by the following formula:
C = εr * A / d

Where:
• C is the capacitance in Farads
• εr is the relative permittivity of the dielectric material
• A is the area of the electrodes
• d is the distance between the two electrodes

The relative permittivity (εr) of the electrolyte is quite low, around 2. The electrodes of an AEC are constructed in a way that many of them are stacked in a cylinder and then rolled up so that the area of the electrodes (A) is increased in relation to their diameter (d) thus increasing the capacitance of the AEC.
