Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also known as an electrolytic capacitors, is a type of capacitor that has a large capacitance per unit volume due to the large dielectric constant (about 5 times larger than ceramic capacitors) of the electrolyte. Aluminum electrolytic capacitors are widely used in power conditioning, signal conditioning, RF blocking, and acoustic crossover networks, as well as many other applications.

MAL215097904E3 Application Field and Working Principle

The MAL215097904E3 is an engineering-grade aluminum electrolytic capacitor that provides excellent performance in high-temperature, solid-state environments. Its value of 4μF (μf) (also referred to as 4mF or mF) is well-suited for AC power circuits, filter circuits, and other applications where ripple currents and high current-carrying capacity are required.

The MAL215097904E3 is an axial-type aluminum electrolytic capacitor and is constructed of a metallic casing and a permeable membrane. Its anode is a thin oxide layer that forms on the anode\'s surface when the capacitor is electrostatically charged. Its cathode is a meshlike wire mesh that wraps around the outside of the anode. The capacitance of the MAL215097904E3 is determined by the amount of electrolyte, the number of layers of the membrane, and the quality and size of the mesh.

The MAL215097904E3 enables the capacitor to achieve higher ripple currents than standard electrolytic capacitors. This is due to its low-impedance characteristics and its high capacitance per unit volume. The combination of these two characteristics enhances the stability of power supply systems, allowing longer life and improved performance.

The MAL215097904E3 also offers a lower ESR (Equivalent Series Resistance) than standard electrolytic capacitors. This is beneficial in applications where small current-ripples are essential because it helps to stabilize the output voltage. It is also capable of withstanding temperatures up to 105°C, ensuring reliability and durability.

Overall, the MAL215097904E3 is an excellent choice for high-performance, high-temperature applications where a high level of reliability and stability are required. It is designed to provide superior performance and a long life expectancy, making it an ideal component for use in industrial, automotive and consumer electronics. applications.
