Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are popularly used in many consumer electronics, communication devices, and motor drives. This type of capacitor is identified by its cylindrical body shape and dual electrical connection. Its cylinder is typically made of aluminum with a surface painted or anodized for protection. Inside the cylinder, there is the electrolyte material, which serves as the medium for holding electrical charge.

The unique characteristic of aluminum electrolytic capacitor lies in its ability to act as an electric power storage medium and as a filter for high-frequency or even low-frequency noise. Its electrical conduction and dielectric properties also make this type of capacitor a reliable choice for many types of applications.

The EKYB101ELL820MJ16S is an aluminum electrolytic capacitor which is characterized by its high volumetric efficiency and is perfectly suitable for applications requiring high capacitance. It is manufactured with 5mm diameter and 16mm length, thermally stabilized E-shaped aluminum-poled (with solid electrolyte), making it suitable for use in many various applications.

Since most aluminum electrolytic capacitors are polarized, the two electrical connection at its leads suggests the direction of current flow through it. One of its lead connections has a negative or lesser potential, or even a mark or line to denote it as such. This is due to the rectifying effect which occurs between the anode and the negatively charged electrolyte material, resulting in the concentration of positive charges at the cathode of the capacitor.

The EKYB101ELL820MJ16S aluminum electrolytic capacitor has an operating temperature range of -40°C to +85°C, a capacitance range from 0.04 μF to 1000 μF, and a maximum operating voltage of 50V. It also has a leakage current of 0.1CV or 5mA (whichever is higher) and a dissipation factor of less than 0.15% at 20°C.

In terms of application, the EKYB101ELL820MJ16S aluminum electrolytic capacitor is best suited for various consumer electronic, communication and motor drive applications in which continuous charging and discharging of electrical energy is required. With its large capacitance, the capacitor can store large quantities of electric power density and can be used to offer greater volumetric efficiency and operates over a wide range of temperatures.

The working principle of an aluminum electrolytic capacitor is based on the same principle as any other polarized capacitor type. Its internal construction comprises two conductive plates (the anode and the cathode) and a dielectric that separates these two plates. The anode is made of aluminum and the dielectric material is the semi-solid electrolyte. This electrolyte allows the electric current to flow in only one direction towards the cathode while keeping the electrons from the anode side away from the other side. When the capacitor is charged, the positive ions of the electrolyte move towards the cathode, leaving an oppositely charged layer on the anode. This process produces electric fields, which serves as the storage medium for the electrical energy. When the capacitor is discharged, the electric fields cause the flow of current and the ions to move back to their original positions.

The EKYB101ELL820MJ16S aluminum electrolytic capacitor is a great choice for applications that require high capacitance and a reliable power storage capacity. It offers a range of features and a suitable operating temperature that makes it suitable for motor drive and many other applications. With its small size, it can also be integrated into small electronic devices to ensure they have reliable power storage.
