Working principle

Aluminum electrolytic capacitors feature an aluminum anode, a paper separator, an electrolyte solution commonly composed of boric acid and borax, and a cathode made of aluminum or other metal oxide. The aluminum anode and cathode serve as the two plates of a capacitor. The electrolyte acts as an insulator between the plates, while allowing the electric charge to flow through the capacitor. Aluminum electrolytic capacitors can be rated to hold a charge of up to 1,000 times higher than a comparable ceramic capacitor. This allows them to store more energy than ceramic capacitors.

228LBB100M2DD aluminum electrolytic capacitor is made of high-quality tantalum oxide anode, enabling it to be highly efficient with a long life cycle. A tantalum oxide anode creates a stable dielectric layer in the electrolyte solution that can hold more charge while being less likely to be deteriorated by the electric field. Furthermore, the nickel-plated steel end cap of the aluminum electrolytic capacitor can further reduce the leakage current and enable the capacitor to continuously deliver rated performance.

With a wide range of operational temperatures, low ESR, long lifetime and high volumetric efficiency, 228LBB100M2DD aluminum electrolytic capacitor is an ideal choice for a variety of power applications.
