Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in a variety of modern electrical and electronic equipment. Aluminum electrolytic capacitors (also known as “electrolytic capacitors” or “polymer capacitors”) are the most popular form of electrical capacitors amongst the numerous capacitor types.

200BXC150MEFCGC16X25 Application Field and Working Principle

The 200BXC150MEFCGC16X25 aluminum electrolytic capacitor is mainly used in audio devices such as head-phones and portable speaker systems, and in applications such as power supplies. The working principle of aluminum electrolytic capacitors is based on the physical phenomenon of electrochemistry to obtain a larger capacitance than a normal capacitor. The key components of this aluminum electrolytic capacitor include an aluminum can, a cathode foil, and an oxide layer which serves as a dielectric.

The capacitor works by charging ions onto the surface of the anode and forming a thin, conductive layer of aluminum oxide. This oxide layer is then used as a dielectric which separates the two electrodes (anode and cathode). When a voltage is applied across the electrodes, electrons are attracted and repelled from the anode and cathode respectively. This causes a current to flow between the two electrodes, thereby creating a capacitance.

The main advantage of this type of aluminum electrolytic capacitor is its relatively large value of capacitance which is obtained from the thin dielectric layer. Also, because of its electrochemical composition, the capacitance is highly stable over time and temperature, and self-healing is achievable. This high reliability makes this capacitor a useful choice for filter network and tuning applications.

The main disadvantage of the 200BXC150MEFCGC16X25 aluminum electrolytic capacitor is its limited shelf life. Because its dielectric is composed of aluminum oxide, it is susceptible to the degradation of chemicals, oxides, and even airborne particulates, which can corrode the dielectric layer and lead to a reduced capacitance value. Therefore, designers must carefully analyze the environmental conditions of where this capacitor is to be used and take necessary measures in protecting against these elements.

Overall, when properly applied and maintained, the 200BXC150MEFCGC16X25 aluminum electrolytic capacitor can provide a higher value of capacitance in comparison to other types of capacitors, making it an ideal choice within its range of application.
