Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are components of electronic circuitry, composed of two aluminum plates separated by a thin dielectric oxide film. They are one of the most widely used types of capacitor due to their high operating temperature range, low leakage current, and wide capacitance range. This makes them suitable for use in many applications including power supplies, audio circuitry, and high-frequency circuits.

686LMB450M2BD Application Field and Working Principle

The 686LMB450M2BD series aluminum electrolytic capacitor is a low-leakage type capacitor that is suitable for use in demanding environments, such as pulse inverters or DC power supplies. It provides high performance in the areas of ripple current, long life and low ESR. Its low-profile and miniaturized design allows for easy installation.The working principle of an aluminum electrolytic capacitor is based on the principle of dielectric polarization. In an electrolytic capacitor, an oxide layer is formed on one of the aluminum plates (the anode), which acts as a dielectric. When a voltage is applied, charges accumulate in the dielectric, resulting in an electric field across the two plates. This electric field stores energy and allows capacitive coupling between the two plates.The 686LMB450M2BD series of aluminum electrolytic capacitor offers high capacitance values in a narrow range and stable capacitance at high temperatures. Additionally, these capacitors feature a low ESR, high ripple current, and long lifetime. This makes them ideal for use in power supplies and switch mode power supplies, where a combination of high voltage and current is needed with reduced space requirements.
