Aluminum Electrolytic Capacitors

The EKXJ451ELL820MU50S is an aluminum electrolytic capacitor. As the name implies, aluminum electrolytic capacitors are capacitors that use electrolytic reaction to store electrical energy. The cylindrical shape and form factor give it a unique look. Inside, two distinct layers of aluminum foil form a sandwich like configuration that is separated by an electrolyte material.

The aluminum foil layers are known as cathode and anode. The anode layer is the inner layer and it carries the positive charge, while the cathode layer is the outer layer and it carries the negative charge. The anode and cathode layers must be separated by an impermeable diaphragm in order to prevent leakage between them and thus, to achieve proper electrical insulation across the device.

The electrolyte material is often a paste-like conductive liquid that fills the entire inner compartment of the capacitor. This liquid is typically made of an organic compound such as ethylene glycol or propylene glycol, with added acid in order to increase its electrical conductivity. The liquid also serves as a protective environment, preventing oxidation of the metal foil layers and preserving their electrical properties over long periods of time.

When exposed to a voltage source, an electrochemical reaction occurs between the two metal layers and the electrolyte, which produces a physical force that pushes together the layers, increasing the electrical capacity of the capacitor and thus, storing electrical energy. This energy can then be used to power small electronic devices.

The EKXJ451ELL820MU50S aluminum electrolytic capacitor offers high capacitance with a tolerance of +/-20%. It has a wide operating temperature range of -55°C to +105°C, which makes it ideal for use in a variety of applications, including power supplies and medical instrumentation. It also has long service life, extending to more than 3,500 hours.

Aluminum electrolytic capacitors are highly reliable and robust, and they are commonly used in a wide range of applications. They are used in power supplies to reduce power loss, to filter signals and to provide protection for sensitive electronic components. They are also often used in audio systems and motor control applications.

In summary, the EKXJ451ELL820MU50S aluminum electrolytic capacitor is a reliable device that provides high capacitance, high tolerance, wide operating temperature range and long service life. With these features, it is suitable for a variety of applications, including power supply and motor control applications.
