Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also referred to as an electrolytic capacitor, is an electronic component comprising two aluminum foils etched with a pattern to increase the surface area to create an anode (positive electrode) and cathode (negative electrode), separated by a dielectric layer around which is wound a non-conductive sleeve. Depending upon the construction and mounting, aluminum electrolytic capacitors offer the largest capacitance values of any type of capacitor and are widely used in electronic circuits in applications such as filtering, decoupling, power factor correction, AC motor run capacitors, and more.The 381LX681M160H042 is a type of aluminum electrolytic capacitor designed for applications that require high levels of capacitance, high operating temperatures, and long life. Due to its small size, this type of capacitor is also ideal for applications where mounting space is limited.The 381LX681M160H042 is a surface mounted aluminum electrolytic capacitor featuring a two-digit code indicating its capacitance in microfarads, voltage rating, leakage current, and other specifications. Capacitance is specified in the first digit, while voltage rating is specified in the second digit. In this case, the first digit indicated a capacitance value of 680µF and the second digit indicated a voltage rating of 16V. The resistor indicates the maximum permissible DC working voltage of the capacitor and the tolerance in the capacitance value. Aside from its standardized code, the 381LX681M160H042 also features a series of letters indicating its case size, operating temperature, housing design and other variables. In the case of the 381LX681M160H042, the “LX” indicated its case size, “M” indicated a maximum operating temperature of 105°C and “H” indicated its cylindrical shape.The most important feature of aluminum electrolytic capacitors is their high capacitance per unit volume. This makes aluminum electrolytic capacitors an ideal choice for applications requiring large capacitance ratings in small spaces. The 381LX681M160H042 was specifically designed for applications that require high capacitance, high temperature operation, and reliable long-term performance.The 381LX681M160H042 aluminum electrolytic capacitors work on the principle of electrolytic action. This involves two aluminum foil electrodes of opposite polarity, separated by a thin layer of oxide film. The aluminum foils are anodized in an electrolytic solution to form an anode and a cathode on the aluminum surface. The oxide film acts as a dielectric, store electric charge, and the electrolytic solution bonds the oxide film to the aluminum surface.When a voltage is applied across the two electrodes, electric charge is drawn to the oxide film and stored within it. The strength of the electric field is determined by the capacitance of the particular capacitor, which is indicated by the code. As capacitance increases, a greater amount of charge can be stored which increases the size of the electric field. A larger electric field can result in a higher operating voltage, higher temperature operation, and more stable performance over time. Aside from their large capacitance ratings, 381LX681M160H042 aluminum electrolytic capacitors offer additional advantages such as their smaller size and their ability to handle high ripple or transient currents. The 381LX681M160H042 is also designed to handle extreme temperatures and offer a long service life. Typical applications for 381LX681M160H042 aluminum electrolytic capacitors include filtering, decoupling, power factor correction and AC motor run capacitors. These capacitors are ideal for applications that require high capacitance, high temperature operation, and long-term reliability.
