Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, or simply an electrolytic capacitor, is a type of capacitor that uses an electrolyte to achieve a larger capacitance than is possible with a dry film or paper construction. The larger capacitance of an electrolytic capacitor can range from 0.00001 mF to 100,000 mF, enabling a wide variety of uses. This type of capacitor is commonly used in audio/video equipment, power supplies, motor control systems, and other electrical applications.The commonly used abbreviation for this type of capacitor is E-caps. The "E" stands for electrolytic because electrolytes are used in their manufacturing process. Most electrolytic capacitors contain a carbon layer on their surface, which is used as a dielectric. Due to the nature of the dielectric layer, electronic signals can travel through the capacitor with minimal loss.The "381LQ391M450K042" is an aluminum electrolytic capacitor specifically designed for use in applications where an extended temperature range and high vibration resistance are required. It is a cylindrical, radial-legged, screw-type capacitor, with a rating of 100 VAC terminal voltage and 0.2A ripple current. Its capacitance is 45 µF and its equivalent series resistance (ESR) is 0.38 ohms.The aluminum electrolytic capacitors are manufactured in a wide variety of sizes and shapes, including cylindrical, axial, snap-in, and more. The body of the capacitor can also be made from a variety of materials, such as aluminum, tantalum, and polyphenylene sulfide. The designations can be deciphered by reading the numbers and letters on the label of the capacitor.In order to enhance their performance, aluminum electrolytic capacitors use a variety of properties, including temperature coefficient, voltage coefficient, temperature characteristics, and self-healing. The temperature coefficient of the capacitor is typically a percentage value, which indicates how much the capacitance of the capacitor increases or decreases with a shift in temperature. The voltage coefficient is a voltage dependent term, which means that the capacitance of the capacitor will decrease as the applied voltage increases. As for the temperature characteristics, this term means that the capacitance of the capacitor will remain constant, despite fluctuations in temperature. Finally, self-healing refers to the ability of the capacitor to repair itself when exposed to an overvoltage.The working principle of an aluminum electrolytic capacitor is relatively simple. In general, a voltage is applied follow by a current. The current passes through the capacitor, first charging it with a positive charge on the anode (or one side) and then discharging it, creating a negative charge on the opposite side. The capacitors are designed to allow only an AC current to pass and to block a direct current as electrons in the electrolyte tend to associate themselves with positive ions. The combination of all these characteristics makes aluminum electrolytic capacitors well-suited for many applications, ranging from audio/video equipment and power supplies to motor control systems. Its ability to tolerate extreme temperatures and operating at high frequency make it the perfect choice for applications which require reliable performance.
