LGJ2E221MELB15

Aluminum electrolytic capacitors are parts made of two aluminum foil and separated by a porous film. Generally, liquid electrolyte is poured into one end of the oxide film and the anode of the aluminum foil is connected to the casing. When the capacitor is connected to the circuit, the electrolyte will penetrate the oxide film and the electronic current will flow through the foil to form a pair of continuous electric double layers. This layer can store energy. Today, we will be introducing the LGJ2E221MELB15 aluminum electrolytic capacitors, including its application fields and working principle.

Application Field

The LGJ2E221MELB15 aluminum electrolytic capacitors are typically used for audio frequency/DC blocking, energy storage, filtering, bypass, decoupling or coupling in many electronic products. The applications range from consumer audio, computer, video, power supplies, LED lighting, automotive, medical, telecom and power transmission.

Also, it is the ideal choice for applications requiring high energy, low ESR, and/or improved impedance. These components are provided with axial leads or specialized termination and a variety of other performance characteristics to meet high-speed circuit requirements and assembly process requirements.

Working Principle

The LGJ2E221MELB15 aluminum electrolytic capacitors are based on the working principle of two aluminum foils separated by a porous film. One of the foils is an anode, to which a conductive electrolytic liquid is connected, and the other is a cathode. When a voltage is applied to the two foils, electronic current will flow and an electric double layer will be created, which stores energy.

The application of these capacitors is based on on the ability of the porous ceramic material and the electrolyte liquid to form a capacitance, which controls the flow of current in the circuit. The capacitance is determined by the size of the two aluminum foil plates, and when a higher capacity is required, the plates can simply be enlarged.

In conclusion, the LGJ2E221MELB15 aluminum electrolytic capacitors are widely used and highly popular for various applications, due to their ability to store electrical energy and control the current flow in a circuit. This makes them the ideal choice for many electronic product designs.
