Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components that are composed of two aluminum plates separated by a dielectric material. The plates are connected to a conductive electrolyte that is usually formed from an acid or alkali solution. They are used in many applications including low-frequency filtering, radio antenna, decoupling, high-frequency DC/DC converters, and power supply holdup/filtering. The MALREKA00DD368EG0K is a specialized aluminum electrolytic capacitor and can be used in a wide variety of applications.

Application Field

The MALREKA00DD368EG0K aluminum electrolytic capacitor is a polarized capacitor that is designed to operate over a wide temperature range and high ripple currents. It is intended for power supply holdup/filteringly in critical applications where size and weight restraints are important considerations. It is also suitable for decoupling and low-frequency filtering applications as well as radio antenna tuners. The combination of its wide temperature range, low ESR, and low impedance makes it suitable for many different applications.

Working Principle

The basic operating principle of an aluminum electrolytic capacitor is similar to that of a conventional capacitor. A voltage is applied across the capacitor plates, and as a result, a current flows through the capacitor. This current charges the capacitor plates and creates an electric field between them. This electric field stores energy in the form of an electrostatic field. The amount of energy that is stored depends on the capacitance value of the capacitor.

An electrolyte, typically an acid or alkali solution, is located between the capacitor plates. This electrolyte is necessary to enable the capacitor to function properly as it helps to transfer the charge between the capacitor plates. The electrolyte also helps to reduce the amount of leakage current, which occurs due to the electrical resistance of the plates. The leakage current can reduce the overall efficiency of the capacitor.

The MALREKA00DD368EG0K aluminum electrolytic capacitor is designed to operate in severe environments such as high temperatures and high ripple currents. It features a low ESR which helps to reduce the winding losses that are commonly associated with power supplies. The capacitor also has a long shelf life and is capable of operating over a wide temperature range. It is a cost-effective solution for applications where size and weight restrictions are important considerations.
