Aluminum Electrolytic Capacitors: ELXY500ELL122ML35S Application Field and Working Principle

Aluminum electrolytic capacitors are a type of capacitor which uses an aluminum foil as its anode, with an etched surface for increased surface area. This type of capacitor is particularly useful for higher capacitances due to its higher surface area to volume ratio. The ELXY500ELL122ML35S aluminum electrolytic capacitor is a high-capacitance capacitor with a working voltage of up to 500V, a capacitance tolerance of +10/-15 percent, and an operating temperature range of -40 to +105 C.

Application Field

The ELXY500ELL122ML35S is an ideal choice for a wide variety of applications including audio, video, and automotive. It is especially ideal for decoupling and filtering applications due to its high capacitance and working voltage. In addition, it can be used in power supplies and in filtering and decoupling applications in low-frequency systems.

Working Principle

The working principle of the ELXY500ELL122ML35S aluminum electrolytic capacitor is based on the generation of electric field when a current is passed through an electrolyte, aluminum foil, and a dielectric. When the dielectric is exposed to the electric field present in the electrolyte, it creates an electric double layer which generates a capacitance. This capacitance is dependent on the area of the aluminum foil, the thickness of the dielectric, and the length of time the current passes through the electrolyte. The ELXY500ELL122ML35S aluminum electrolytic capacitor is specifically designed to combine the highest possible capacitance with a relativelystable temperature coefficient. To this end, the aluminum case has a dielectric layer of aluminum oxide, which is formed in a chemical reaction when the aluminum foil is subjected to an electric field. By virtue of this layer, the capacitor is able to store a large amount of energy, and to maintain a low temperature coefficient.

Advantages and Disadvantages of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors offer several advantages over other types of capacitors. The first is their relatively high capacitance for their size. This allows them to offer a higher capacitance than other types of capacitors for a given volume, making them ideal for applications with limited space. In addition, these capacitors are relatively inexpensive, making them a cost-effective choice. Their major disadvantage is their relatively high leakage current, which is due to the presence of aluminum oxide layer on their surface. As a result, these capacitors can be prone to self-discharging, particularly if the working voltage is close to their max voltage rating.

Conclusion

The ELXY500ELL122ML35S aluminum electrolytic capacitor is an ideal solution for many applications requiring high capacitance, high working voltage, and a relativelystable temperature coefficient. It is ideal for applications where limited space is available, as it offers a great capacitance to volume ratio. It also offers a cost-effective solution for many applications. However, aluminum electrolytic capacitors should be chosen with care, as their relatively high leakage current can cause them to self-discharge.
