ECA-2CM470

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized capacitors which use a solid electrolyte to achieve very high capacitance values. This type of capacitor consists of two aluminum foils which have been etched to form a pattern of small interlocking fingers. The fingers are then separated by a thin insulating material. A conductive liquid electrolyte is then introduced, which allows ions to pass between the layers carrying an electric charge. When voltage is applied, a current will flow through the capacitor, which increases the capacitance.

The ECA-2CM470 aluminum electrolytic capacitor is a capacitor which provides a high capacitance at a very low ESR (equivalent series resistance). This capacitor is ideal for low frequency applications, where high capacitance and low ESR are desired. The capacitor also has a very low leakage current, making it a suitable choice for applications where high voltage must be maintained for long periods of time.

The ECA-2CM470 capacitor has a wide range of applications and can be found in power supplies, audio equipment, medical systems and electronic test equipment. In electronic test equipment, the ECA-2CM470 is frequently used for smoothing power, buffering digital signals and providing reversible DC power, making it an excellent choice for a wide range of applications.

Working Principle

The working principle of the ECA-2CM470 aluminum electrolytic capacitor is based on the fact that electrolyte (chemical compound which carries electrical charge) is introduced between two aluminum foils. When voltage is applied, current flows through the capacitor, which causes a reaction which increases the capacitance.

By controlling the thickness of the electrolyte and the spacing between the two aluminum foils, the capacitance of the capacitor can be changed. This allows for the creation of special types of capacitors for different types of applications. The ECA-2CM470 capacitor is designed specifically for low-frequency applications, allowing it to provide a high capacitance and low ESR.

In most applications, the ECA-2CM470 aluminum electrolytic capacitor is connected in series with other components, such as resistors and inductors. This connection allows the capacitor to store and supply energy to the other components when needed. This energy is then released slowly, as the capacitor discharges and the other components are able to use the stored energy.

The capacitance of the ECA-2CM470 capacitor can be changed by adjusting the applied voltage. The higher the voltage, the more electrons will be transferred between the aluminum foils, leading to a higher capacitance. Conversely, the lower the voltage, the fewer electrons will be transferred and the capacitance will be reduced.
