Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the type of capacitors most widely used today. They are available in a variety of sizes, shapes, and capacitance values, and used for various consumer applications such as cell phones and TVs. This article will discuss the application field and working principle of a specific type of aluminum electrolytic capacitor, the EKXJ161ELL121MU20S.

Application Fields

The EKXJ161ELL121MU20S aluminum electrolytic capacitor is mainly used in a range of high-precision electronic applications, such as digital power supplies and LED lighting, as well as other types of compact power supplies, power inductors, and transformers. Additionally, it can be used to enhance the power output of audio amplifiers or for board level filtering.

Working Principle

The EKXJ161ELL121MU20S aluminum electrolytic capacitor works on the principle of electrochemical reaction between the anode and electrolyte. An oxide film is formed on the anode when a positive potential is applied to it, and the electrolyte acts as the medium between the oxide layer and the surface of the anode. This oxide layer acts as the dielectric layer in the capacitor and the charge carriers, which are stored in the oxide layer, establish an electric field between the anode and the electrolyte.The EKXJ161ELL121MU20S aluminum electrolytic capacitor is specially designed with a cylindrical design and its two electrodes are aligned, which can provide better power density. The two electrodes are further separated by a non-conductive elastomer sealant, resulting in a smoother electrical performance and better thermal management than other types of capacitor.

Durability and Safety Performance

The EKXJ161ELL121MU20S aluminum electrolytic capacitor has a durable design due to its superior quality material and construction. It is also designed with an overpressure valve for extra safety and for protecting the capacitor against surges and reverse voltages. In addition, its solid construction helps to reduce internal resistance and to improve the capacitor\'s operational stability.The EKXJ161ELL121MU20S aluminum electrolytic capacitor also offers a high level of safety performance with its non-flammable and halogen-free construction. This helps to ensure that the capacitor does not pose any health hazards in the event of a rupture or damage. Additionally, it is also designed to meet the requirements for the RoHS (Restriction of Hazardous Substances) directive. In conclusion, the EKXJ161ELL121MU20S aluminum electrolytic capacitor is an ideal choice for high-precision electronic applications, thanks to its superior operational stability, durability, and safety performance. Its solid construction and the use of non-flammable, halogen-free materials make it a reliable and safe choice for a variety of electronic applications.
