Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in today’s electronics and electrical circuit designs. They are used as filters, coupling and decoupling capacitors across the power and signal lines of electronics and electrical systems. This article will discuss the application and working principle of the LKX2W221MESB35 aluminum electrolytic capacitor.

Applications

LKX2W221MESB35 aluminum electrolytic capacitors are mainly used to filter noise and energy storage in power supply systems, they help to decouple AC and DC to smooth waveform transition, and protect against AC ripple because of their small size and high capacitance. They can also be used in DC-DC converters, micro-processors, and automatic control systems.

The main features of the LKX2W221MESB35 aluminum electrolytic capacitor include its long life, high ripple current, low impedance, and the capability to withstand temperatures ranging from -55°C to 85°C. Additionally, these capacitors exhibit a wide range of capacitance values ranging from 6.3µF to 220µF, with a working voltage of 35V and 63V, making them suitable for low voltage applications.

Working Principle

LKX2W221MESB35 aluminum electrolytic capacitors are typical non-polar AC and DC applied capacitors, it is composed of two aluminium foils rolled and metallized onto an insulation paper. The two aluminium foils are separated by an electrolyte solution. One of the capacitor’s electrodes is connected to the external circuit, it is called the anode electrode, while the other one, called the cathode electrode, is kept isolated from the external circuit. The dielectric between the two aluminium electrodes is the electrolyte solution, the electric current flows through the aluminium foil and is blocked by the electrolyte solution so it does not reach the other electrode and cannot discharge the capacitor.

The capacitance of the LKX2W221MESB35 aluminum electrolytic capacitor is dependent on the cross-sectional area of the electrodes, the thickness of the aluminium foil, and the type and amount of the electrolyte. The capacitance of the capacitor also changes with the applied voltage and it decreases with increased frequency. This capacitors are used in more complex circuits such as filters, power supplies, and other similar applications where the capacitance needs to be stable even under various load conditions.

In conclusion, the LKX2W221MESB35 aluminum electrolytic capacitors are versatile components with a wide range of uses in electronics and electrical applications. Their small size and high capacitance make them ideal for low voltage applications such as DC-DC converters and micro-processors, while their long life, high ripple current, low impedance, and temperature capability makes them suitable for various applications. This article has provided an overview of the application and working principle of the LKX2W221MESB35 aluminum electrolytic capacitor.
