Aluminum electrolytic capacitors, also known as ‘’electrolytic capacitors’’, are a special type of capacitor that uses an anode of aluminium foil, a dielectric of oxidized aluminium and a liquid electrolyte as its working principle. The EKYB800ELL391MK25S capacitor, in particular, is an aluminum electrolytic capacitor. It is often used in low voltage applications and is characterized by its non-polarized behavior, long operational lifetime and low effective series resistance (ESR).The EKYB800ELL391MK25S capacitor is mainly used in a variety of low voltage applications, including signal conditioning, high stability buffering, transient filtering and surge suppression. Its ability to handle extreme temperatures, low ESR and low inductance make it an ideal choice for applications in the automotive and industrial fields.In terms of its working principle, the EKYB800ELL391MK25S capacitor utilizes an anode of aluminium foil and a dielectric of oxidized aluminium. The integrity of the oxide layer is maintained by the liquid electrolyte, which reacts with the aluminium oxide, creating an energy barrier that prevents current from flowing through the dielectric material. When a voltage is applied on the capacitors’ terminals, the oxide layers on the electrodes oxidize, forming a barrier that charges the capacitor. This stored energy can then be released when the voltage is removed, and the capacitor discharges.The EKYB800ELL391MK25S capacitor also features low ESR, which means it is able to handle higher current-switching frequencies, as well as a more consistent discharge time. It also features an extended operational lifetime, and is capable of withstanding extremely high temperatures. Last but not least, its non-polarized behavior makes it a suitable choice for designs that require multiple directions of current flow.In summary, EKYB800ELL391MK25S is an aluminum electrolytic capacitor used in low voltage applications such as signal conditioning, high stability buffering, transient filtering and surge suppression. It features a dielectric of oxidized aluminium, an anode of aluminium foil and a liquid electrolyte, and is characterized by its non-polarized behavior, low ESR, extended operational lifetime and ability to handle extreme temperatures.
