Working principle

The EGXF630ELL391MK20S is an aluminum electrolytic capacitor that works by storing electrical energy in a layer of aluminum oxide formed on the surface of the aluminum electrodes. This enables the capacitors to have larger capacitance than other types of capacitors. Additionally, the aluminum oxide layer acts as an insulator, preventing current leakage and increasing the lifespan of the capacitor.

When an electric field is applied across the aluminum electrodes, the formed aluminum oxide layer creates an insulated barrier that stores the electric energy. As current is applied, the dielectric layer expands and contracts to store and release energy, according to the direction of current. As a result, the capacitance of the capacitor will decrease or increase depending on the level of current applied.

The EGXF630ELL391MK20S operates in a wide temperature range, from -25°C to +105°C. This is due to its special design, which allows it to maintain its properties at extreme temperatures. Additionally, the EGXF630ELL391MK20S utilizes the latest technology, such as miniaturization and high capacitance, providing extended lifespan and performance.
