The LAQ2G181MELA40 capacitor is a type of aluminum electrolytic capacitor (AEC). AEC’s are electrical components used to store energy in an electrical circuit. They are characterized by their ability to store a large amount of energy and handle high levels of current in a relatively small package.The LAQ2G181MELA40 is a very popularly used capacitor in a variety of applications, including motor control, charge/discharge systems, power supplies, voltage regulation and other power circuit designs. It has a rated voltage of 16 VDC, a temperature range of -55°C to +105°C and a maximum operating temperature of 85°C.The LAQ2G181MELA40’s construction is a flexible aluminum shell and a two-terminal device with two conducting plates separated by a layer of solid dielectric material. The capacitor is filled with an electrolytic solution that allows electrons to move freely between the two plates. This is known as the Faraday effect and is what allows the capacitor to store energy.The LAQ2G181MELA40 can be used in a variety of applications, such as DC-link capacitors, pulse capacitors, surge suppressors, DC blocking capacitors and other specialized power system applications. In these applications, the capacitor acts to store energy and protect electrical components from high voltage spikes or noise.The working principle of the capacitor involves a few properties. Firstly, the dielectric material allows for charge storage. Every time a voltage is applied to the capacitor, electrons are pumped from the positive plate to the negative plate, thus creating a charge difference between them. This charge difference is then stored in the capacitor and can then be discharged when needed.The second property involves the electrolyte. This liquid medium acts as a barrier between the two plates, preventing the electrons from flowing directly between them. This allows the stored charge to maintain its magnitude over time.Finally, the capacitance of the capacitor is dependent on the size of the plates, the thickness of the dielectric material and the type of electrolyte used.In summary, the LAQ2G181MELA40 aluminum electrolytic capacitor is an ideal choice of capacitor for a wide range of applications due to its combination of high voltage and current handling, large energy storage capacity and low thermal resistance. The capacitor works on the four principles of charge storage, the Faraday effect, the electrolyte barrier and plate capacitance.
