Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are commonly used in electronic equipment, including consumer electronics, computers, and audio applications. They are typically used to store and release energy, filter signals, dampen transients, or to act as an energy reservoir in power applications. Aluminum electrolytic capacitors are electrochemical capacitors with large capacitance values in small sizes, making them an ideal choice for many applications.

B43504E0187M002 Capacitor Application Field and Working Principle

The B43504E0187M002 aluminum electrolytic capacitor from EPCOS is a non-solid electrolytic capacitor with very low impedance. This makes it a perfect choice for use in high frequency and avalanche protection circuits. The capacitor is also able to handle high voltage, up to 630V, and can also handle high ripple current. The B43504E0187M002 capacitor is available in sizes ranging from 8 to 22 µF, and in ratings from 6.3V to 630V. This makes it ideal for a wide variety of applications, from audio equipment to automotive electronics. The working principle of an aluminum electrolytic capacitor is based on the physical phenomena of electrolysis. It consists of two aluminum foils, separated by an oxide film. These foils are then rolled up and placed inside a metal can. The electrolyte used in the capacitor is usually organic, but can also be an aqueous solution of ammonium borate.The wettable layer of aluminum oxide on the plates serves as a dielectric material, which allows current to flow when a voltage is applied between the two plates. The electrochemical reaction between the electrolyte and the aluminum foils cause a very thin oxide film to form on the surface of the aluminum foils. This film acts as a barrier, only allowing current to flow when a voltage is applied to the plates. The B43504E0187M002 is especially advantageous in the automotive industry, due to its ability to withstand vibration, heat, and corrosion. In addition, this aluminum electrolytic capacitor has excellent self-healing characteristics, which makes it ideal for use in ripple current and overvoltage protection applications. As an aluminum electrolytic capacitor, the B43504E0187M002 has a large capacitance range, is available in a variety of sizes, can handle high voltage, and has excellent self-healing characteristics that make it ideal for automotive and electronic applications that require a reliable and robust capacitor.
