Aluminum Electrolytic Capacitors

38LR681M250A022 aluminum electrolytic capacitors are passive components that use the dielectric of aluminum oxide to store electrical energy. They are commonly found in consumer, motor-drive, and power supply circuits and consist of two metal plates separated by an insulator. Typically, they are cylindrical in shape, involve no moving parts, and come in a variety of sizes and capacitance values.

Application Field

38LR681M250A022 aluminum electrolytic capacitors are widely used in consumer electronics such as laptops, tablets, mobile phones, and other appliances. They are also used in bigger machines used in industrial applications, including AC and DC motors, wind turbine generators, electronic tools, and lighting fixtures. They also appear in a variety of other electronic systems, ranging from lighting ballasts and solar energy panels to audio equipment and air conditioning systems.

Working Principle

The 38LR681M250A022 aluminum electrolytic capacitor is made up of two metal plates separated by an ionically conductive electrolyte, with one facing external and the other facing internal. The metal plates are separated by an oxide film, which forms on one side due to an anodization process and also serves as the dielectric. When voltage is applied, the anode and cathode form a capacitor with capacitance value.

The electrolyte conducts ions in an electrostatic field between the anode and cathode. This process results in the formation of a layer of oxide film on the anode and also releases electrons back into the circuit, allowing for current to flow. When the external voltage is removed, the oxide film breaks down, ending the current flow.

The values of the capacitance of the 38LR681M250A022 aluminum electrolytic capacitor depend on several factors, including the surface area of the metal plates and the thickness of the oxide film. This is why manufacturers have to carefully select the right materials and process parameters in order to produce capacitors with high capacitance values.
