Aluminum Electrolytic Capacitors

Capacitors are electrical components that are used to store energy and increase the power of the system. Aluminum electrolytic capacitors (AECs) are the most popular type of capacitors and are mainly used in power supplies and DC inverters.

LNX2W183MSEK Application Field and Working Principle

The LNX2 W183MSEK is a kind of axial-lead aluminum electrolytic capacitor. It is most suitable for wide temperature applications which require high load impact and high seating temperature capability. Its capacitance range from 2.2uF to 10000uF and voltage rating from 16V to 500V DC, making it an ideal choice for a wide range of applications.

The aluminum electrolytic capacitor consists of an anode foil, cathode foil, and an electrolyte solution between them. The anode foil is etched to create a large surface area and increase the capacitance and current handling capability. The cathode foil is usually made of aluminum and contains a heterogeneous electrolyte solution. The electrolyte consists of the aluminum oxide, which provides insulation between the anode and cathode, and the organic solvent, which ensures proper dissolution of the oxide.

The working mechanism of an aluminum electrolytic capacitor is quite simple and efficient. When a voltage is applied, the electrodes at both sides will be positively charged, allowing electrons to flow through the capacitor. The electrons form a metallic film that separates the anode and cathode, creating a charge-storing dielectric layer composed of an electrically insulating aluminum oxide layer. The anode and cathode electrodes remain physically separated, but the charge allows them to have a measure of electrical connection, allowing capacitance to develop in the dielectric.

The charge stored in the dielectric layer is proportional to the applied voltage, making the capacitance of an AEC also proportional to the voltage. At high temperatures, the electrolyte evaporates and dissipates itself, reducing the size of the dielectric layer and decreasing the capacitance. This decrease in capacitance is known as “soakage."

The LNX2W183MSEK capacitor is particularly suited for automotive, industrial, and consumer applications. In automotive applications it is used for pulse discharge capacitance in vehicles for noise reduction and vibration control, and in motor control systems for providing the required current to start motors. In industrial applications, it is used for oscillators, power transmitters, power supplies, and medical equipment. In consumer applications, it is widely used in power tools, personal computers, home appliances, and entertainment equipment.

The LNX2W183MSEK capacitor has a long expected shelf life, making it a popular choice for many applications. This type of capacitor also has low ESR values, which minimizes power losses and improves the efficiency of the system. The high cycling performance and wide temperature range make it a suitable choice for many different applications. Finally, the overall robustness of the capacitor ensures that it is suitable for extreme temperature applications.
