LKSH2472MESA

Aluminum electrolytic capacitors are a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. The LKSH2472MESA is a popular type of aluminum electrolytic capacitor and is often used for applications requiring higher capacitance than traditional tantalum or ceramic capacitors.

The structure of an aluminum electrolytic capacitor consists of two aluminum foils separated by a paper spacer impregnated with the electrolyte. The aluminum foils are coated with an oxide layer which acts as the dielectric material. The electrolyte is usually an acidic solution or polymer that facilitates ionic movement between the two foils. This allows for a higher capacitance than with other types of capacitors.

The LKSH2472MESA is a standard 24mm diameter, long lifetime aluminum electrolytic capacitor. It has a loss tangent of 0.121 and a maximum operating temperature of 85°C. This allows for higher ripple currents and long life in cyclic applications. It is available in a variety of capacitance ratings and voltage ratings ranging from 35V-450V. The LKSH2472MESA is also RoHS compliant.

In terms of application field, the LKSH2472MESA is mainly used in switched mode power supplies, high frequency communication circuits, frequency circuits, etc. These applications require high capacitances in comparison to traditional tantalum or ceramic capacitors. The high capacitance also makes the LKSH2472MESA ideal for applications such as power converters, line filtering and noise suppression. It is also used in consumer electronics such as computers, television sets, refrigerators and more.

The working principle of an aluminum electrolytic capacitor is based on the Faraday law of electrolysis. This law states that an electric current flowing through an electrolyte will cause a reaction between the electrolyte and the electrodes, resulting in the accumulation of electrical charge on the electrodes. The accumulation of charge creates a voltage across the electrolyte, and this voltage is in turn used to store the electrical energy. The capacitance of the aluminum electrolytic capacitor is determined by the thickness of the oxide layer, as well as the size of the electrodes.

In conclusion, the LKSH2472MESA is a standard aluminum electrolytic capacitor with long life, high capacitance and low loss tangent. It is often used in applications requiring higher capacitance than traditional tantalum or ceramic capacitors. The working principle of the aluminum electrolytic capacitor is based on the Faraday law of electrolysis which allows for accumulation of electrical charge on the electrodes.
