Aluminum electrolytic capacitors are the most common type of electrolytic capacitors with the highest capacitance per unit volume. SEK472M025ST is one of the most popular products in this type of capacitor category. The SEK472M025ST is an aluminum electrolytic capacitor with an operating temperature range of -40 to +105°C and is a preferred choice in many applications.The SEK472M025ST aluminum electrolytic capacitor can be used in many different applications. It has the capability to provide large capacitances in a small form factor, thus making it ideal for space constrained areas. It is commonly used in DC link filtering, input filtering, switching power supply filter networks, high ripple current applications, high inrush current filters, and motor start circuits.The SEK472M025ST aluminum electrolytic capacitor consists of two aluminum plates separated by a dielectric oxide layer. The oxide layer acts as the dielectric material and provides insulation between the plates which prevents current flow between them. The electrolytic solution is present on both the aluminum plates which aid in forming the oxide film. The electrolytic solution also protects the oxide layer from corrosion and minimizes leakage current.The working principle of a SEK472M025ST aluminum electrolytic capacitor is based on the capacitor’s capacitance. The capacitance is defined as the ability of a capacitor to store energy in the form of an electric field. This electric field is created by a change in electric charge across the plates, where the amount of charge accumulating on each plate is proportional to the capacitance. When a voltage is applied across the plates, the electric field is created, allowing the capacitor to store energy. The capacitance of the SEK472M025ST aluminum electrolytic capacitor is rated at 4750uF at 25V.The SEK472M025ST is an ideal choice when applications require large values of capacitance in a small form factor. It is reliable and has a long service life which makes it a preferred choice in many applications. Additionally, the electrolytic solution present on the plates provides protection against corrosion and reduces leakage current, making it suitable for high ripple current applications.
