Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that uses an electrolyte (usually manganese dioxide or a combination of manganese dioxide and sulfuric acid) to maintain a polarized electrical field between its plates, consisting of an aluminum foil layer lined with a layer of electrolytic dielectric material. Due to this design, aluminum electrolytic capacitors are able to hold a larger charge than traditional capacitors. This makes them ideal for use in applications where a large capacitance and high surge current are required.

The MAL203861331E3 features a maximum rated voltage of 450V, a high rated capacitance of 3000uF, and high ripple current and temperature stability. The MAL203861331E3 uses a stable conformal coating that provides a high degree of moisture and corrosion resistance and improves its reliability. The MAL203861331E3 is also designed to reduce EMI and RFI emissions, making it suitable for use in a wide range of power applications. The MAL203861331E3 operates on the principle of a traditional aluminum electrolytic capacitor. When a voltage is applied across its two terminals, the electrolyte between the capacitor’s plates acts as a dielectric, which produces an electrical field between the two. This electrical field creates a barrier between the two plates, which prevents the charge from dissipating. The higher the applied voltage, the greater the charge capacity, and the higher become the MAL203861331E3’s capacitance. The MAL203861331E3 is a highly durable capacitor designed for use in a variety of high-power applications. Its solid aluminum construction and conformal coating provide excellent reliability in hot and humid environments. The MAL203861331E3’s high ripple current and temperature stability also make it suitable for hostile environments.
