Aluminum Electrolytic CapacitorsAn aluminum electrolytic capacitor is an electronic component that uses the physical behavior of an electrolyte, combined with that of a porous aluminum oxide layer, to store electrical charge.Aluminum electrolytic capacitors are often referred to as “polarized capacitors” because they must be connected to the correct polarity in order to function correctly. Aluminum electrolytic capacitors are mainly composed of a rigid aluminum can (which acts as the anode), a roll or cylindrical foil (which acts as the cathode) and an electrolyte (which acts as the dielectric).The aluminum electrolytic capacitor model 380LQ221M400J022 is a surface mount aluminum electrolytic capacitor. It features a polarized design, compact casing, and wide operating temperature range, making it suitable for use in a variety of electronic applications.The 380LQ221M400J022 aluminum electrolytic capacitor has a maximum capacitance of 22 µF and a rated voltage of 4VDC. It has a small form factor with a diameter of 3.6 mm and a height of 2.1 mm, making it perfect for use in tight spaces. It has a wide temperature range of -25 to +85℃, enabling its use in a variety of operating environments. Furthermore, it has a long shelf life of 2000 hours at 85℃, making it highly reliable and durable. The 380LQ221M400J022 aluminum electrolytic capacitor is mainly used in applications such as power filtering in power supplies and audio equipment, signal noise reduction in switching power supplies, and other switching circuits. Additionally, due the long shelf life, low impedance, and low leakage current of this type of aluminum electrolytic capacitor, it is suitable for use in automotive, military and industrial applications.The working principle of an aluminum electrolytic capacitors involves the formation of an electrolytic film on the surface of the anode, which increases its surface area, thus increasing its capacitance. This is achieved by passing an electric current through the electrolyte and over the anode, which acts as a catalyst to produce the desired effect. The electric current is generated through a combination of current, voltage, and time. The electric current passes through the electrolyte which serves as the dielectric material and is attracted to the anode. It passes through the electrolyte and eventually produces an electrically conductive aluminum oxide film on the surface of the anode. This film is negatively charged, hence the term “polarized.” The aluminum oxide film acts as an additional dielectric material and increases the capacitance of the capacitor.In summary, the 380LQ221M400J022 aluminum electrolytic capacitor is a polarized capacitor, typically used in applications such as power noise filtering and signal noise reduction. It has a compact form factor with a long shelf life, making it highly suitable for a variety of operating environments. Additionally, its working principle involves the formation of an electrolytic film on the surface of the anode, thus increasing its capacitance.
