LKG2A182MESAAK

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electronic components widely used in a variety of electronic equipment and systems. As its name implies, they are made of an aluminum housing that is filled with an electrolyte of water and organic solvent, and an electrolytic paper is used to insulate the electrodes.

The LKG2A182MESAAK is one of the most widely used aluminum electrolytic capacitors with a wide variety of applications. It has a metalized polyethylene-naphthalate film dielectric, making it suitable for use in a wide range of operating temperatures, from -25A°C to +105A°C. The LKG2A182MESAAK has a voltage rating of 28V DC, capacitance of 18000µF and a ripple current rating of 3A.

Application Field

The LKG2A182MESAAK is one of the most widely used aluminum electrolytic capacitors and has a wide range of applications. It is often used in DC power supplies and regulators, automotive and other transport equipment, communications and other signal processing equipment, as well as industrial and consumer electronics. It is often used in applications where low-leakage or long-life is required.

Working Principle

The working principle of aluminum electrolytic capacitors is based on the fact that the electrolyte inside the capacitor acts as an electrical insulator. This insulating property blocks the flow of current until the external voltage exceeds a certain value. This voltage is known as the "turn-on" voltage and is usually greater than the rated voltage of the capacitor.

When the external voltage exceeds the "turn-on" voltage, current begins to flow and charge accumulates. The rate at which the charge accumulates is determined by the capacitance of the capacitor. As the capacitor charges, the voltage builds up and eventually reaches a point where it is equal to the external voltage. At this point, the capacitor is said to be fully charged and the current stops flowing. The capacitor remains charged until the external voltage is dropped, at which point the charge begins to dissipate and the capacitor discharges.

The working principle of an aluminum electrolytic capacitor is the same as that of any other type of capacitor, but its construction and materials make it particularly well suited for use in a variety of applications. The use of electrolytes, electrodes, and dielectrics together with the ability to withstand harsh environmental conditions make aluminum electrolytic capacitors very versatile and reliable.
