Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are capacitors with one or three aluminum bodies as long as one tenth of a millimeter thick, and there are several hundred to several hundred to several hundred to several hundred to several thousand dielectric layers on the surface. The aluminum electrolytic capacitor is a kind of electric energy storage component used in a variety of applications such as electronic devices, mobile devices, and power systems. Each of the capacitors in the family has good DC motor performance, high working voltage, high capacity, and low ESR (Equivalent Series Resistance).

25YXF220MEFCTA8X11.5

The 25YXF220MEFCTA8X11.5 is a family of aluminum electrolytic capacitors that combines all the characteristics of aluminum electrolytic capacitors described above. It stands out among all aluminum electrolytic capacitors and provides reliably low ESR and low temperature drift characteristics. The 25YXF220MEFCTA8X11.5 family includes 12 different types of electrolytic capacitors that range in capacitance from 0.47μF to 1000μF and in rated voltage from 16V to 1000V.

Application Field

Aluminum electrolytic capacitors have a wide range of applications. They are often used in rectifier circuits, power supplies, power electronic systems, highly reliable circuits, UPS systems, frequency converters, digital signal interfaces, audio systems, supply filters, and other devices that require high current or high temperature. The 25YXF220MEFCTA8X11.5 family can be applied in electronic circuits such as power supplies for industrial equipment, medical equipment, and communications networks that require low ESR for high reliability and stability.

Working Principle

The 25YXF220MEFCTA8X11.5 family of aluminum electrolytic capacitors utilizes a spacer separating the anode and the cathode to prevent a short-circuit and allow the build-up of electric charge. The anode is composed of an aluminum foil with a coating made from manganese dioxide and is connected to a liquid electrolyte. The voltage drops across the anode will cause oxygen ions to move across the electrolyte and react to form a manganese oxide layer on the surface of the anode, which further increases the electric field. The cathode is made from a conductive foil that is connected to a liquid electrolyte. When a positive voltage is applied to the anode, electrons will travel through the electrolyte to the cathode, resulting in a charge separation that creates an electric field. When the voltage applied to the anode decreases, the reaction between oxygen ions and manganese dioxide reverse, and the electric charge is released.

Conclusion

The 25YXF220MEFCTA8X11.5 family of aluminum electrolytic capacitors combines optimal performance, reliability, and stability. Its application fields include power supplies for industrial equipment, medical equipment, and communications networks that require low ESR for high reliability and stability. The capacitors use a combination of an anode made of an aluminum foil with a coating of manganese dioxide, along with a cathode of a conductive foil, and liquid electrolyte to achieve a consistent charge separation and electric field.
