Aluminum electrolytic capacitors are among the most important components for many power electronics applications. Depending on the application, different types of capacitors can be used with unique specifications and features, such as long life, high capacitance, and low leakage current. The LAS2G331MELB35 aluminum electrolytic capacitor is a popular choice for defense applications that require high- reliability, high-temperature operation.

An aluminum electrolytic capacitor consists of an anode, typically made of aluminum foil, a cathode made of aluminum oxide, and an electrolyte to facilitate conductivity between both electrodes. The oxide layer on the aluminum acts as a dielectric separating the two plates, allowing the capacitor to store energy. When direct current (DC) is applied to the capacitor, the electrolyte is electrochemically decomposed, allowing electrons to flow between the anode and the cathode, and thus creating an electric field. This separation of electrons is what allows the capacitor to store charge.

The LAS2G331MELB35 aluminum electrolytic capacitor is a low-profile, high-temperature, radial leaded type designed specifically for defense applications with high requirements of temperature, vibration, shock, humidity, humidity cycling, storage, and solderability. The capacitor is capable of storing large amounts of charge while operating in temperatures up to 105°C and has a long lifetime of over 10,000 hours. The capacitor also allows for low leakage currents and a maximum ESR of 0.08 Ohm at 25°C.

The LAS2G331MELB35 aluminum electrolytic capacitor has a capacitance of 330μF, which makes it suitable for high-power applications in the defense sector, including power supplies, high voltage pulse generators, and other power conditioning equipment. The aluminum electrolytic capacitor also works well in space-constrained applications, thanks to its small size and low-profile height. It features a ripple-current rating of 5A (105°C) and a voltage rating of 35V.

The maintenance of such capacitors is essential in order to keep them performing at their best. This is done by cleaning the capacitor with a di-electric compound, like isopropyl alcohol, before re-soldering it in place. This will help reduce the oxidation that accumulates on the electrodes of the capacitor. Aluminum electrolytic capacitors should also be monitored for gradual increases in leakage current, which can be caused by wear in the dielectric layer. When the leakage current exceeds the specified limits, it is time to replace the capacitor.

The LAS2G331MELB35 aluminum electrolytic capacitor is the ideal choice for defense applications that require high-reliability and high temperature operation. It is capable of storing large amounts of charge and operating in temperature extremes, allowing it to provide reliable performance for even the most demanding applications.
