Introduction to Aluminum Electrolytic Capacitors

A capacitor is an electrical device that stores energy in the form of an electric field. It is composed of two plates of conductive materials separated by an insulating medium called the dielectric. An aluminum electrolytic capacitor (also referred to as an aluminum electrolytic, an electrolytic, or an aluminum electrolyte) is a type of capacitor that uses an electrolyte to achieve a larger capacitance per unit volume than other types. The aluminum electrolytic capacitor was developed in the 1930s and has since become the most widely used type of capacitor in electronic devices.

What is LQR2W182MSEGBN?

LQR2W182MSEGBN is a type of aluminum electrolytic capacitor manufactured by Honda Electronics Co. Ltd., a Japanese company specializing in the manufacture of high quality, innovative and reliable aluminum electrolytic capacitors. It is an axial lead ultra-low impedance capacitor that is designed for use in high frequency and high current applications. It is capable of achieving a capacitance of 182uF and a working temperature range of -25°C to +125°C. The capacitor features low equivalent series resistance (ESR) and wide capacitance temperature characteristics.

LQR2W182MSEGBN Application Field and Working Principle

The main application fields of LQR2W182MSEGBN aluminum electrolytic capacitors are computer, communication, automotive, consumer electronics, medical, photoelectric, high frequency and other electronic fields. The working principle of the capacitor relies on the formation of an electrical double layer at the interface between the electrolytic solution and the electrodes. A voltage applied across the capacitor initiates the migration of electrons across the double layer. This creates a charge separation and a potential difference which causes a current to flow through the capacitor. The current flow creates the capacitor’s electric field which stores the energy. The aluminum electrolytic capacitor is composed of three parts: the anode, the dielectric and the cathode. The anode is an aluminum foil that is dip coated with an electrolytic solution. The dielectric is an oxide layer formed on the anode during manufacturing and it serves to insulate the anode and cathode from each other. The cathode is typically made of a conductive material such as nickel, or a mixture of nickel and zinc. When a voltage is applied to the LQR2W182MSEGBN aluminum electrolytic capacitor, the electrolyte solution and the dielectric between the anode and the cathode act as the dielectric. The dielectric allows charge carriers to move freely between the anode and the cathode while insulating the anode and cathode from each other. This creates an electric field that stores the electrical energy. The capacitance of the capacitor is determined by the size of the electrodes and the thickness of the dielectric.

Conclusion

LQR2W182MSEGBN aluminum electrolytic capacitors are high frequency, high current devices that are suitable for a variety of applications. They are composed of an anode, a dielectric and a cathode and use an electrolyte solution to create an electric field that stores the electrical energy. They are widely used in the computer, communication, automotive, consumer electronics, medical, photoelectric and other electronic fields.
