Aluminum electrolytic capacitors are electrolytic capacitors that are made up of two aluminum foils separated by a non-conductive dielectric combined with an electrolyte. Aluminum electrolytic capacitors use a polarized component as the main body, which is generally composed of a positive pole plate, a negative pole plate and a liquid electrolyte. The aluminum foil of the positive pole plate served as the anode is etched to form a porous structure surface, and a thin layer of oxide film is formed on the surface of the aluminum foil in the manufacturing process. The oxide film serves as a dielectric, and the negative pole plate consists of aluminum foil, brass plates, etc. The negative pole plate is placed on the top of the positive pole plate after being insulated from the electroforming liquid and is surrounded by the electrolyte. The anode and the negative pole of the capacitor form an electric double layer between them, which is equivalent to a pair of energy storage plates.

The 50PX3.3MEFC5X11 aluminum electrolytic capacitor is a high-grade, high-performance aluminum electrolytic capacitor. It is mainly used in products such as power supplies, servers, and computer motherboards. Its main characteristics are low ESR, high corrosion resistance and long life. The rated voltage of the 50PX3.3MEFC5X11 aluminum electrolytic capacitor ranges from 6.3V to 100V, and its capacitance range is from 18μF to 395μF.

The working principle of the 50PX3.3MEFC5X11 aluminum electrolytic capacitor is mainly based on the polarization effect of the metal and the electrolyte. The positive pole of the capacitor is the anodic metal plate, and the negative pole of the capacitor is the bottom metal plate immersed in the electrolyte. The two metal poles of the capacitor are not connected directly, but separated by a dielectric oxide film formed by the polarization of the electrolyte. When a small direct current is applied to the capacitor, ions in the electrolyte are attracted by the two metal poles, and a film of charged ions is formed at the interface between the metal pole and the oxide film, which is called “polarization double layer”. The electric double layer formed by the positive charge and the negative charge forms an electric field in the space separated by the oxide membrane, allowing energy to be stored in the capacitor, greatly increasing its capacity.

In summary, the 50PX3.3MEFC5X11 aluminum electrolytic capacitor is a high-performance capacitor mainly used in power supplies, servers and computer motherboards. Its operating principle is based on the polarization effect of the metal and the electrolyte. When an electric current is applied to the capacitor, charge forming a film at the interface between the metal pole and the oxide film and a electric double layer is formed, which can separate the positive and negative charges and store energy, thus greatly increasing its capacity.
