Aluminum Electrolytic Capacitors are a type of capacitor that uses solid aluminum and aluminum oxide as the plates, separated by an electrolyte. The 420QXW100MEFR16X31.5 is an electrolytic capacitor in a radial case, meaning the connections are made from the side of the capacitor rather than the end. This type is suitable for surface mounting, making it a great choice for applications where space is at a premium.This aluminum electrolytic capacitor is rated at 100μF with a working voltage of 16 volts and a maximum working temperature of 105°C. The 420QXW100MEFR16X31.5 has robust construction, offering superior temperature, voltage, and ripple current capability as well as accuracy, reliability, and endurance. With an outer diameter of 3.15mm and a height of 6.5mm, it has excellent capacitance stability at high temperatures and a low equivalent series resistance (ESR).Aluminum electrolytic capacitors, in general, have a number of applications. They are used extensively in power electronic circuits for filtering or blocking DC power to AC signals, for controlling voltage spikes, and for energy storage. They are also used in Smart Grid technology, automotive power conversion circuits, motor drives, uninterruptible power supplies, LED lighting power supplies, and more.Working Principle The working principle of an aluminum electrolytic capacitor is based on the fact that two metal plates separated by an electrolyte will vary in capacitance, depending on the voltage applied to them. The two metal plates are made from a thin strip of aluminum, which is separated from one another by a dielectric material. The electrolyte also acts as a dielectric, though its capacitance may vary depending on the voltage applied to the plates.The metal plates are exposed to an electrolyte, and when an electric current is applied, electrons move from one plate to the other and are stored on the opposite plate. This is known as charge separation, and the amount of charge stored is dependant on the capacitance of the aluminum electrolytic capacitor.Further, the capacitance of the aluminum electrolytic capacitor is dependent on the voltage applied. As the voltage increases, the capacitance increases; as the voltage decreases, the capacitance decreases. Over time, as the electrolyte gradually evaporates, the capacitance decreases. This is why it is important to use aluminum electrolytic capacitors with the correct working voltage rating, so the capacitance remains stable and consistent. In addition, the schematic symbol for an aluminum electrolytic capacitor is a pair of short parallel lines pointing in opposite directions, with the positive line represented by an arrow. The arrow indicates the flow of positive charge. The 420QXW100MEFR16X31.5 aluminum electrolytic capacitor is primarily used for filtering high-frequency switching power supplies and controlling voltage spikes. Its low equivalent series resistance (ESR) and excellent capacitance stability at high temperatures make it an optimal choice for applications such as switching power supplies and uninterruptible power supplies, LED lighting power supplies, automotive power conversion circuits, and more. With the right voltage rating and a robust construction, the 420QXW100MEFR16X31.5 aluminum electrolytic capacitor is a great option for a variety of applications.
