Aluminum electrolytic capacitors (also known as electrochemical capacitors) are passive components that are used to store energy electrically in a wide array of electrical appliances and equipment. They are composed of two aluminum foils insulated with a paper separator. These foils act as the anode and cathode of an electrolyte material, and an aluminum or aluminum alloy cylindrical casing is used to seal the package. When DC voltage is applied across the capacitors, the anode serves as a (-) cathode and the cathode serves as a (+) anode for charging, and a dielectric layer is formed on the anode surface, decreasing the resistance of the capacitor.

EKMQ251VSN821MR35S capacitors incorporate a solid, non-soluble, electrolyte and have a wide range of applications due to their high capacitance and high levels of stability and reliability. Typical applications for EKMQ251VSN821MR35S capacitors include DC-DC converters, computer motherboards, laptop battery charging, etc. The working principle of these capacitors is simple, consisting of two aluminum plates separated by an electrolyte material and a solid dielectric material, such as ceramic or titanium oxide.

When a DC voltage is applied to the capacitor, an electric field is established through the dielectric material, causing a surface charge to accumulate on the two aluminum plates. This charge is continuously updated with the current flow, and will result in a buildup of electric energy over time. This electric energy is then released back into the circuit when the voltage is removed.

Due to their high levels of reliability and stability, EKMQ251VSN821MR35S capacitors are commonly used in industrial, automotive, and medical applications, where their outstanding performance is highly valued. In addition, their low ESR characteristics and operating temperature range make them ideal for use in high-frequency switching mode power supplies, allowing for reduced size and weight.

Furthermore, the EKMQ251VSN821MR35S capacitors are more tolerant to voltage transients than other aluminum electrolytic capacitors, making them more suitable for use in applications that require high levels of capacitive stability and reliability. Additionally, they are also well suited for use in low frequency signal filtering applications, due to their low ESR characteristics.

Overall, aluminum electrolytic capacitors of the EKMQ251VSN821MR35S series offer reliable, high-performance solutions for a range of electrical and electronic applications. Their wide operating temperature range and low ESR characteristics make them highly suitable for use in high-frequency switching mode power supplies, and their excellent capacitive stability and reliability make them ideal for industrial, automotive, and medical applications.
