Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in various applications and are classified within the electronics industry. An aluminum electrolytic capacitor, such as the EDK476M035A9GAA, consists of two aluminum foils, two solid electrolyte layers, and a separator soaked in an electrolytic solution. The two foil electrodes are both made from aluminum, and the electrolyte used is usually a combination of ethylene glycol and boric acid. Aluminum electrolytic capacitors take advantage of the phenomenon of dielectric absorption, which is the process of electrical charge coming into contact with – and then dissipating through – an insulating medium. This process is most efficient with aluminum based electrolytic capacitors.

The Application Field of EDK476M035A9GAA

The EDK476M035A9GAA is an aluminum electrolytic capacitor with a capacitance of 47uF and a maximum working voltage of 35V. It is typically used in DC applications, such as motor drives and audio equipment, where high reliability and long life are required. It is also used in general-purpose filtering circuits, power supplies, audio amplifiers, and other applications that require long life and stable capacitance. This capacitor is capable of handling high frequencies, temperatures, and voltage ranges. The EDK476M035A9GAA offers a good cost to performance ratio, making it suitable for use in a range of applications.

Working Principle of EDK476M035A9GAA

The EDK476M035A9GAA operates using the dielectric absorption process, as mentioned previously. This is the same process used by all aluminum electrolytic capacitors, and it enables the capacitor to store and release a large amount of energy. When the capacitor is initially charged, the two aluminum foils become polarized, with one side becoming positive and the other becoming negative. When direct current is applied, the positive and negative charges begin to move through the electrolyte. This creates a dielectric absorption effect, which results in the capacitor storing electrical energy. When the capacitor is discharged, the electrical energy is released back into the circuit.

The dielectric absorption process is heavily reliant on the quality of the electrolyte used. Poor electrolyte quality can result in unstable performances and inconsistent energy storage capacity. As a result, it is important that the electrolyte used with the EDK476M035A9GAA aluminum electrolytic capacitor is of superior quality. Fortunately, the electrolyte used with this capacitor is an ethylene glycol and boric acid solution, which offers excellent performance.

Conclusion

The EDK476M035A9GAA aluminum electrolytic capacitor is a popular and reliable choice for many applications, such as audio amplifiers, motors drives, and general-purpose filters. Its dielectric absorption process enables it to store and release electric energy, and the quality of the electrolyte used in its construction ensures superior performance. Thanks to its excellent cost to performance ratio, theEDK476M035A9GAA is suitable for use in a wide range of applications.
