Aluminum electrolytic capacitors feature long life expectancy and high volumetric efficiency as compared to standard types of capacitors. The LQSW6221MELZ45 is a type of aluminum electrolytic capacitor that further advances these features and offers superior performance, design flexibility and value. This article will discuss the application field and working principle of the LQSW6221MELZ45.

The LQSW6221MELZ45 is suitable for high reliability circuits, automated test systems and motor control systems. Specifically, it provides superior power performance in automotive and similar applications. It boasts a long life expectancy of up to 5,000 hours at a temperature of 105°C and also offers electrical parameters that are stable over a wide temperature range. Additionally, it highlights a patented design for superior nuisance impedance, improved delivery, and a package offering savings of board area.

Working Principle: The LQSW6221MELZ45 is an aluminum electrolytic capacitor with a negative electrode that is in contact with a dielectric layer of an electrolyte. When electrical energy is applied to the electrode, and the electrolyte is formed, the electrolyte acts as both a positive and a negative electrode. As a result, a capacitance is created between the two electrodes. The capacitance value depends on the thickness of the dielectric layer, and the area of contact between the electrode and the electrolyte. Furthermore, the device also has an anode and a cathode. When electrical energy is passed through the capacitor, electrons move from the anode to the cathode to create a short duration electrical current.

The LQSW6221MELZ45 aluminum electrolytic capacitor also offers additional features such as its low leakage current. Low leakage current ensures that the capacitor does not lose energy when it is not in use. Additionally, the capacitor is designed with a high safety margin, meaning that it can be used in extreme environments without encountering any damage. Finally, its low ESR (Equivalent Series Resistance), ensures it produces a high energy density – the amount of energy stored in the capacitor per given volume.

In summary, the LQSW6221MELZ45 aluminum electrolytic capacitor offers superior performance, value and design flexibility. Its long life expectancy and volumetric efficiency make it suitable for high reliability circuits, heated systems and motor control systems. Furthermore, it produces a low leakage current, a high safety margin and a low ESR, giving it a high energy density.
