Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a type of capacitor relying on an aluminum oxide film with high dielectric strength as the dielectric, making it able to support very high electrical stresses. It is often used in power supplies for this reason. The EKMS501VSN820MQ30S is a type of aluminum electrolytic capacitor.

Application Field

The EKMS501VSN820MQ30S capacitor is used in a wide range of applications. It is an aluminum electrolytic capacitor, making it suitable to be used as general-purpose capacitors for specific needs in different types of power supplies. Furthermore, due to its specific properties, it can be employed in off-line applications that require a very high surge current capability. Finally, it is particularly suited for non-automotive equipment operating in an environment that requires a mid-level temperature range.

Working Principle

The EKMS501VSN820MQ30S capacitor works in the same way as any other aluminum electrolytic capacitor. An aluminum oxide film is used as the dielectric, which has a much higher dielectric strength than paper or mica capacitors. This allows the capacitor to support higher electrical stresses. As the capacitor is filled with electrolyte, any electrons that pass through the oxide film will be blocked, thus creating a corresponding electric field in the capacitor.

The aluminum oxide is formed by immersing an aluminum foil in an electrolyte solution. This is known as anodization, and it forms a thin protective film of aluminum oxide, which acts as an insulator, preventing the electrons from passing through the layers of the capacitor. The polarization of the capacitor and the resulting electric field determine the capacitance of the device. When a voltage is applied to the terminals of the capacitor, the electric field increases. This increases the capacitance of the capacitor.

The EKMS501VSN820MQ30S capacitor has a special feature, which is known as the surge current capability. This is due to the addition of an extra capacitor packing element (such as a ceramic core) that is placed between the cathode and the anode of the capacitor. This ceramic core increases the degree of protection and allows the capacitor to withstand much higher surge currents.

Conclusion

The EKMS501VSN820MQ30S capacitor is a special type of aluminum electrolytic capacitor that is suitable to be used in various applications. Its surge current capability makes it particularly suitable to be used in non-automotive equipment. Its aluminum oxide dielectric layer makes it able to support higher electrical stresses than paper or mica capacitors, allowing it to be used in applications with a mid-level temperature range.
