In terms of performance, this capacitor has an exceptionally wide voltage range and impressive current capacity, along with long-lasting endurance in harsh conditions.
The most common application field of an aluminum electrolytic capacitor is in high voltage and high current rectification circuits, as well as alternating current circuits with AC voltages up to 500V. Examples of devices using such capacitors include home appliances, office equipment, industrial power supplies, and many other electronic devices. Additionally, these capacitors are often used in high frequency DC-DC converters, with the purpose of blocking the higher frequency ripple and preventing the low frequency component passing through. As such, they are widely used in areas where consistent DC power is required, such as medical imaging systems, scientific research, and power supply systems.
The working principle of an aluminum electrolytic capacitor is relatively straightforward, using the electrostatic field generated by electrical charge to store electrical energy. When voltage is applied across the capacitor, electrical charge is stored between two metal plates – the positive plate being the capacitor’s anode, and the negative plate serving as the cathode. The capacitor’s dielectric medium is a thin oxide layer created by the chemical reaction between the electrolyte solution and the metallic plates.
This oxide layer effectively seals out air, thus preventing oxidation of the metal plates, and reducing the amount of energy that can be discharged from the capacitor. As the electrical charge is stored on the capacitor plates, the oxide layer works to maximise the energy that can be stored – often acting as a “dielectric filter”, eliminating unwanted electric currents, such as harmonics or electrical noise.
In terms of design, EKMR401VSN121MP25S is an exceptionally robust capacitor, with its advanced design techniques ensuring high reliability and dependable performance.
