EET-ED2W181BA

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrochemical capacitors with a larger capacitance per unit volume than other types of capacitors. They have an anode made of pure aluminum with a layer of aluminum oxide, sometimes called "alumina," on its surface, and a cathode of either an aluminum or a nickel-plated steel. The capacitor is filled with an electrolyte, usually aqueous or organic, and sealed. The electrolyte is a conductive medium that allows current flow between the two electrodes and also serves as an insulation layer between them.

EET-ED2W181BA Application Field and Working Principle

EET-ED2W181BA is a polarized aluminum electrolytic capacitor with snap-in mounting type and rated voltage of 25V. It is designed for use in the fields of automotive electronics, lighting control, motor drive, remote control, and home appliances.

The working principle of the EET-ED2W181BA capacitor is based on electrolysis. It stores energy in the form of an electrical charge between two conductive plates, the anode and the cathode. The anode plate is made of aluminum and is covered with a layer of aluminum oxide. The layer of oxide serves as an insulator between the anode and the electrolyte. When an external voltage is applied, an electric field is developed between the anode and the cathode. This electric field results in the movement of electrons between the plates, producing a charge on the capacitor.

The capacitor works by packaging two or more electrodes together and filling the space between them with an electrolyte, which enables current flow between the electrodes. Electric charge is stored in the form of an electric field in the electrolyte, which is generated by the two electrodes. When a voltage is applied, the electric field moves the electrons and ions within the electrolyte, resulting in a current flow.

The capacitance of the capacitor is determined by the surface area of the electrodes, the distance between them, and the dielectric constant of the electrolyte. The capacitance of the EET-ED2W181BA capacitor is typically between 4.7µF and 1000µF.

The EET-ED2W181BA capacitor is designed for use in applications where high frequency switching and high temperature operations are required. It is designed for use in harsh environments, such as automotive and industrial applications. It also has excellent withstand voltage, reliable life expectancy, and good frequency characteristic.

In conclusion, the EET-ED2W181BA capacitor is a valuable and reliable component of the aluminum electrolytic capacitors family. It is capable of performing high temperature and high frequency operations, while also providing long-term reliability and low ESR. It is ideal for applications such as lighting control, motor drive, and remote control.
