Aluminum Electrolytic Capacitors and their Application Field and Working PrincipleAluminum electrolytic capacitors are components used in electrical and electronic circuits to store electrical energy temporarily and release it when needed. They are produced from aluminum oxide (Al2O3) powder, and consist of two metallic plates separated by a non-conductive and highly viscous material. One of the plates acts as the anode, whereas the other serves as the cathode. The anode is then connected to a thin, thin layer of electrolytic solution or compound that has been applied to the ceramic material, resulting in a dielectric layer which separates the two metallic plates. When the capacitor is connected to a voltage source, a current will pass through the anode, electrolyte, and cathode, resulting in the anode and electrolyte combination to become polarized. The ions in the electrolyte travel towards the cathode, which causes an electrochemical oxidation of the aluminum, resulting in the electrons being ejected and the positive charge being retained. This process creates an electrical charge that is stored within the insoluble aluminum layer. Aluminum electrolytic capacitors are mainly used for power supply filtration, which means that, through their high capacity and low ESR, they are able to reduce ripple and noise from a power supply’s output. Other applications include power supplies for medical equipment, camera systems, computers, and consumer electronics. The most popular type is the 381L/R681M/200J series, which offer a range of capacitance from 0.1 uF to 1000 uF, with a direct current minimum of 6.3V and a maximum of 100V.The 381L/R681M/200J series capacitors offer a number of advantages, the foremost being their compact size and the ability to produce them in low cost volume. This type of capacitor has high energy density and can provide a very stable output. The capacitors have been especially popular among audio equipment manufacturers, as they have also been found to improve sound quality. In terms of their working principle, the 381L/R681M/200J capacitor passes electric current through the electrolyte and then to the cathode. The electrons ejected from the anode plate by the oxidation process accumulate on the cathode, resulting in a charge being build up on the opposite side. However, if the electric current is removed, the voltage across the capacitor is retained for a period of time. This is know as the ‘time constant’ of the capacitor, and is a measure of its efficiency in storing electrical energy.Despite their popularity, aluminum electrolytic capacitors have some drawbacks. They are prone to failure due to high temperature, are more expensive than other types of capacitors, and can be easily damaged by high frequency variations. Such variations can be caused by even small voltage changes, as the capacitor is liable to self-heat, leading to an increased risk of failure.In conclusion, aluminum electrolytic capacitors are a reliable and cost-effective solution in the field of power supply filtration and can be used to reduce the ripple and noise in a variety of applications. The 381L/R681M/200J series, in particular, offer an excellent combination of quality and performance, providing robust and long-lasting performance.
