Aluminum electrolytic capacitors are polarized capacitors whose anode electrode is made of a metal with a recipient electrolyte by electrolysis. The oxide layer formed the cathode on the aluminum foil is the capacitor dielectric. Aluminum electrolytic capacitors are mainly used for filtering, impulse decoupling or energy storage in power supply circuits. The type 450BXA22MEFC18X20 aluminum electrolytic capacitor has a wide application range from small signal filtering to power supply circuits and working principles.

The 450BXA22MEFC18X20 aluminum electrolytic capacitor is composed of black organic insulation paper sleeve, can-shaped aluminum shell, aluminum foil, dielectric absorbing fluid, special impregnated paper and sealing glue, etc. The aluminum foil and impregnated paper are spiral-wound in the capacitor. An electrolytic solution is filled in the combined structure with several electrodes in the center of the aluminum foil and impregnated paper.

The working principle of 450BXA22MEFC18X20 aluminum electrolytic capacitor is mainly composed of anode and cathode areas. When the anode and cathode of the capacitor are connected to positive and negative poles of a DC power supply respectively, the anode causes electrolytic reaction in liquid electrolyte in the capacitor. A thin insulation oxide film is formed on the aluminum foil. The electrolyte combines with the dissolved aluminum to form a liquid conductor. Meanwhile, the anode is anode polarized, the electrolyte generates a certain electric field pressure to compress the existing oxide film, forming a dielectric, resulting in an electric storage effect.

The 450BXA22MEFC18X20 aluminum electrolytic capacitor has wide application fields in the filters for DC power supply, video each equipment, high-frequency communication equipment, musical instruments, LED lighting, Automotive electronics, household appliances, air conditioning equipment, medical equipment, etc. It can provide excellent self-healing characteristics and increased low impedance capacity while requiring relatively low-cost and long-term reliability.

The 450BXA22MEFC18X20 aluminum electrolytic capacitor is widely used in electromagnetic interference functions, such as input capacitor in constant voltage power supplies, DC filter, power supply ripple filter, motor start capacitor, audio crossover, etc. By connecting an appropriate rated resistor in series with the capacitor, it can be used as a time constant in various timing circuits and pulse shaping circuits, thereby enriching the product function and performance. It is also used in the early stages of the audio signal transmission process to eliminate or reduce background noise, interference and distortion.

In a nutshell, the 450BXA22MEFC18X20 aluminum electrolytic capacitor has a wide application range and excellent performance. The working principle is simple and clear, it can reduce the size and cost of circuits, making it well-suited for use in DC power supply filters, audio signal transmission and timing circuits, etc.
