Aluminum electrolytic capacitors are electronic components which are significant for their superior electrical character and low ESR (equivalent series resistance). The LGG2D222MELC40 is an aluminum electrolytic capacitor mainly used for DC link applications like power supplies, inverters, and charged coupled amplifiers. It offers a wide capacitance range of 2.2μF, voltage range up to 50V, and tolerances of up to ±20%.

Construction

The LGG2D222MELC40 consists of three primary parts which are:

• Anodized aluminum case
• Electrolyte
• Electrode

The anodized aluminum case is sealed and contains a paper separator. Electrolyte, a liquid or solid electrolyte determines the capacitance, is added inside the case. The electrodes are made up of an aluminum foil rolled into a spiral coil and an aluminum layer is formed after anodization.

Working Principle

When a voltage is applied to the LGG2D222MELC40, electrons flow from the negative to the positive electrode. This flow of electrons causes an electric current to flow. Hence, the capacitor stores electrical energy and has the property of holding the voltage until it is consumed or the capacitor is discharged.

As the current is passing through the electrolyte, it produces a capacitive effect which means that an electric field is created between the two electrodes. This electric field is generated by the charge stored in the capacitor’s anode and cathode. The size of the electric field is determined by the capacitance value of the capacitor. As the charge builds up, the capacitor becomes more charged and the electric field between the two electrodes increases.

The capacitance of the LGG2D222MELC40 is determined by the size of the aluminum electrodes and separator as well as the electrolyte used. The greater the area of the electrodes and separator, the larger the capacitance of the capacitor. It has a range of 2.2μF and is ideal for applications requiring high voltage, wide capacitance ranges and low ESR.

Application Field

The LGG2D222MELC40 is mainly used for DC link applications such as power supplies, inverters, and charge-coupled amplifiers. It is also used in many other applications such as filtering and noise suppression, which require large capacitance values.
