Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are type of non-polarized electrolytic capacitors. They are widely used in various electronic devices due to their high capacitance-to-weight ratio and long life cycles. The most common material used to construct aluminum electrolytic capacitors is aluminum foil.The 400RX302.2MT78X11.5 is an aluminum electrolytic capacitor with a voltage rating of 400 VDC and a capacitance of 302.2 µF. It features a low ceramic body made of aluminum oxide dielectric and an extended life span due to its self-healing properties. Aluminum electrolytic capacitors are used as power supplies for circuits due to their long life cycles and high efficiency. Additionally, they can be used to reduce leakage current, provide decoupling, and reduce noise. The aluminum construction also makes aluminum electrolytic capacitors more resistant to shock and vibration than other traditional capacitors. The working principle of Aluminum electrolytic capacitors is based on the oxidation of the aluminum anode. The anode of an electrolytic capacitor is made of a thin aluminum foil layer that is exposed to an electrolyte, while the cathode is a paper or plastic material soaked in the electrolyte. When a voltage is applied across the foil, ions in the electrolyte begin to move towards the anode. This process creates an electric field between the anode and cathode which moves the ions back and forth. When a large enough electric field is created, a thin layer of aluminum oxide is formed on the surface of the aluminum foil. This oxide layer serves as a dielectric layer, allowing the capacitor to store an electrical charge, but also preventing the charge from leaking out. Electrolytic capacitors are typically small in size and have a very high charge storage capacity. In summary, the 400RX302.2MT78X11.5 aluminum electrolytic capacitor is a versatile device that is used for a variety of electronic applications. Its high capacitance-to-weight ratio and long life cycles make it a reliable source of power for circuits. Additionally, its aluminum construction makes it tougher and more resistant to shock and vibration. Finally, its working principle is based on the oxidation of the aluminum anode in an electrolyte solution, allowing the capacitor to store a large charge and preventing leakage current.
