Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors have been widely used in many aspects of our life due to their excellent features. Among them, LKX2E681MESA50 is one of the most popular types. It is characterized by its high capacitance, long-term reliability, good thermal stability and more.

Application Field

LKX2E681MESA50 aluminum electrolytic capacitors are mainly used in computer motherboards, power supplies, LCD displays, and other sensitive electronic control systems. It is specifically designed for applications that require an extremely high degree of accuracy in positioning and peak currents, such as in precision timer circuits. In addition, its use of lower ESR makes the capacitors more suitable for high-impedance circuits such as in low-voltage power supply circuits.

Working Principle

The LKX2E681MESA50 aluminum electrolytic capacitors use an electrolytic liquid as the dielectric material, which means that a large number of negative charges are released into the liquid from the relatively thin aluminum oxide film. This makes the large capacitance possible. In addition, the use of a liquid dielectric also helps the capacitor achieve excellent thermal stability. The combination of the thin aluminum oxide layer and the electrolytic liquid makes the capacitor highly stable both electrically and thermally.

When the circuit is powered, the electric current passes through the two metal plates known as the anode and the cathode. The electrolytic liquid is attracted to the positive plate, forming a solid electrolyte thin-film between the electrodes. This thin-film acts as a barrier that prevents current from passing through, allowing only the electrostatic field to remain. This electrostatic charge is stored, resulting in a change in capacitance.

The use of an electrolytic liquid as the dielectric material means that the electric current in the circuit is always flowing in one specific direction. This enables the capacitor to be used in applications where precise control of the current is crucial. The liquid also plays a major role in maintaining the overall temperature of the internal components of the capacitor, and in protecting them from any potential damage due to electricity.

The use of an electrolytic liquid as the dielectric material in LKX2E681MESA50 aluminum electrolytic capacitors provides numerous advantages, including high capacitance, long-term reliability, good thermal stability, and precision control of current. This makes the capacitors an ideal choice for a variety of applications, particularly those that require precise circuit timing and an efficient power system.
