Aluminum Electrolytic Capacitors

LKG1V222MESYBK

Aluminum electrolytic capacitors are a type of electrical capacitor with an electrolytic technology that uses a solid aluminum anode, a liquid or semi-solid electrolyte which acts as the cathode, and an aluminum oxide or other oxide film as the dielectric for energy storage. They are widely used in power-supply filtering, DC blocking, snubbing, and other applications where high capacitance values and long service life are required.

Application field

Aluminum electrolytic capacitors are used in a wide range of industries such as communications, consumer electronics, computing, automotive, industrial, and military/aerospace. The LKG1V222MESYBK is primarily designed for use in high-performance applications such as switching power supplies, inverters, motor drives, motors/generators, UPSs, and as power rail decoupling/smoothing elements.

Working principle

Aluminum electrolytic capacitors work by storing electrical energy in an electrolytic solution that separates two metal foils. The foil closest to the solution is the anode and the other is the cathode. A voltage applied to the anode creates an electric current that produces an oxide film on the anode. This oxide film acts as a dielectric which creates a space between the anode and the cathode to store electrical charge.

The size and design of the capacitor corresponds to the amount of energy it can store. The capacitance value of an electrolytic capacitor is usually higher than of a ceramic capacitor of similar dimensions. This is owing to the fact that the oxide film on the anode serves as a dielectric layer, increasing the available volume and quantity of charge storage. Additionally, due to the addition of a di-electric, aluminum electrolytic capacitors are usually rated for higher voltage ratings compared to a similar sized ceramic capacitor.

Aluminum electrolytic capacitors typically have low ESR (Equivalent Series Resistance) values, making them suitable for filtering applications that require low impedance. However, they tend to be more expensive than ceramic capacitors and their lifespan is considerably shorter. Aluminum electrolytic capacitors are also prone to electric leakage due to aging and environmental conditions. As such, they require frequent checking and periodic replacement for proper operation.

In conclusion, aluminum electrolytic capacitors are widely used in modern electric and electronic designs due to their high capacitance values, low ESR values, and wide voltage ratings. The LKG1V222MESYBK is a specialized type of aluminum electrolytic capacitor that is mostly used in high-performance applications such as switching power supplies, inverters, motor drives, motors/generators, UPSs, and power rail decoupling/smoothing elements.
