Aluminum electrolytic capacitors are often used in electronic equipment. The LKX2E821MESB40 is a type of aluminum electrolytic capacitor designed to meet a wide range of applications. It is a low-profile, surface-mount, polymer aluminum electrolytic capacitor with an external sleeve made from epoxy material. Its main features include high ripple current, high capacitance, low ESR, long life, and excellent electrical and thermal stability.The LKX2E821MESB40 aluminum electrolytic capacitor has a maximum operating temperature of 125°C and voltage rating of 8.2VDC. It is designed to provide excellent performance in both DC and AC applications and is ideal for use in DC/DC converters, power supplies, and other switching systems. The LKX2E821MESB40 is certified to UL 94V-0 for flammability and safety.The working principle of the LKX2E821MESB40 aluminum electrolytic capacitor is based on the electrolytic reaction of a liquid electrolyte mixed with a solid aluminum anode and a porous separator. An electric current is passed through the liquid electrolyte solution and produces a small electrical charge on the anode. This electrical charge accumulates instead of flowing away. The electrolyte then reacts with the aluminum anode, forming a formation of a metal oxide layer on the surface of the anode, called the oxide layer. This oxide layer acts as an insulator and creates a barrier to the electrons on the anode.When a voltage is applied to the aluminum electrolytic capacitor, a charge is created on the anode and the electrons migrate, or move, to the cathode. The idea behind the aluminum electrolytic capacitor is that the charge can be stored and regulated for a longer period of time than with other types of capacitors. The anode layer breaks apart into smaller particles creating a greater surface area for the charge to be stored. This gives the aluminum electrolytic capacitor a higher capacitance and ESR.The LKX2E821MESB40 aluminum electrolytic capacitor is extremely versatile and is suitable for use in a variety of applications. It is often found in power supplies, battery back-up systems, and inverters. Additionally, it is ideal for use in DC/DC converters, AC-DC power supplies, high power switching systems, and transistors.The LKX2E821MESB40 aluminum electrolytic capacitor is not only designed for high performance, but it also offers an extended lifecycle. It is designed to last up to three thousand hours with minimal de-rating, which is significantly longer than other capacitors of its kind. Its extended lifecycle, low ESR, and high capacitance make it the ideal choice for applications that require reliable performance over a long period of time. The LKX2E821MESB40 aluminum electrolytic capacitor is an ideal choice for a variety of applications. It offers high capacitance, long lifecycle, and low ESR, all of which make it a great option for power supplies, battery back-up systems, and other switching systems. Additionally, its epoxy material and UL 94V-0 rating ensures it is highly reliable and safe to use.
