Aluminum electrolytic capacitors, abbreviated as "AEC", are capacitors used in a variety of electronic circuits for a variety of applications. AECs are polarized capacitors and have a positive terminal and a negative reference. The positive terminal is called the anode while the reference is the cathode. The basic construction of an aluminum electrolytic capacitor is composed of a core consisting of two metal plates, an electrolyte, and a dielectric layer which consists of anoxidized aluminum oxide.

860020774014 aluminum electrolytic capacitors are commonly used in DC-DC converters, as they are capable of providing high capacitance and low ESR (equivalent series resistance), allowing for an efficient transfer of power from one circuit to another. These capacitors are also used in audio system solutions to provide an even frequency response. In addition to offering superior AC performance, 860020774014 aluminum electrolytic capacitors have an incredibly high temperature rating of up to 105°C, making them suitable for many high-temperature applications.

The working principle of 860020774014 aluminum electrolytic capacitors involves a combination of chemical reactions and physical processes. These processes occur at the anode and cathode, and play an important role in the operation of the capacitor.

The anode is the positive terminal of the capacitor and is composed of an aluminum sheet. An oxide layer is then deposited on the aluminum, which acts as an insulating medium. This oxide layer is electrochemically formed when current is passed through the aluminum sheets. The oxide layer is very thin, and provides a dielectric for the capacitor.

The cathode is the negative terminal of the capacitor and is composed of a metal plate. Electrolyte liquids are used to fill the gap between the anode and cathode. These electrolytes are usually an aqueous solution of potassium hydroxide (KOH), but other solutions can also be used.

When a voltage is applied to the capacitor, a chemical reaction takes place between the anode, cathode, and electrolyte. This chemical reaction forms a layer of ions which are attracted to the anode and cathode, producing a charge distribution that generates an electric field across the oxide layer. The electric field creates a capacitor which is capable of storing electrical charge energy for a short period of time.

860020774014 aluminum electrolytic capacitors are used in a wide range of applications, such as DC-DC converters, motion control systems, and high-voltage power supplies. They are well suited for these applications due to their ability to provide high capacitance, low ESR, and excellent AC performance.
