Aluminum electrolytic capacitors (AECs) are widely used across a variety of electronic applications due to their low cost, large capacitance, and long shelf life. The LKS1K472MESA is a robust aluminum electrolytic capacitor designed for long-term performance in hi-reliability applications. In this article, we will explore the application field and working principle of this capacitor.

The LKS1K472MESA is an axial aluminum electrolytic capacitor rated for up to 450VDC. It is suited for demanding applications that require hi-reliability, such as automotive, audio, test and measurement, industrial, and communications. The product features a design using highest-quality materials, strict assembly procedures, and rigorous quality control to ensure long-term reliability. The capacitor has a full range of capacitance values from 22 uF to 100 uF, and features a wide operating temperature range from -55°C to +105°C. From a size perspective, it comes in an extremely compact design that is ideal for applications in small spaces.

The internal construction of an aluminum electrolytic capacitor consists of two aluminum foil sheets, separated by an electrolytic paper saturated with electrolyte solution. The positive foil is sandblasted for enhanced corrosion resistance, and the negative foil is non-deteriorating. The two aluminum foils act as the two electrodes and serve as the primary source of capacitance. The electrolytic paper is a sheet of paper that is impregnated with an electrolytic solution, which helps to reduce ESR and provides a uniform electrical field between the two plates.

When a voltage is applied to the capacitor, the positive foil is oxidized, forming an oxide layer on the surface of the aluminum. This oxide layer acts as an insulating barrier between the plate and the electrolyte. The capacitance is formed as an electric field forms between the electrode and the electrical charges are stored in the oxide layer. This capacitance is maintained until the capacitor is discharged and the voltage drops.

The LKS1K472MESA is well-suited for a variety of applications that require high-reliability and long-term performance. It is ideal for automotive, audio, test and measurement, industrial, and communications applications where long-term reliability is essential. The capacitor’s robust construction and wide range of capacitance values make it a great choice for applications that require hi-reliability and long-term performance.
