Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors are widely used in electronic products. Capacitors are commonly found in analog and digital circuits. As such, they have a range of applications, from power conditioning and energy storage to signal processing and filtering. One such capacitor is the SK220M016ST, a radial lead type physically small and is used in a variety of applications due to its compact size.The SK220M016ST is designed to offer good electrical characteristics. Its rated voltage is 16V and its rated capacitance is 220 µF. The maximum capacitance error, 10%, is less than the industry standard of 20%. This, in turn, results in enhanced performance of any application the capacitor is integrated into. Additionally, it has a low dissipation factor (ESL), and a frequency constant of 16 KHz, making it particularly well suited for AC applications.In terms of size, the SK220M016ST is both physically small and lightweight. It is an eight-leg vertical capacitor with a diameter of only 7mm and a thickness of 5mm. This allows it to be easily integrated into the circuit design. Furthermore, its radial lead structure ensures a strong connection between the capacitor and the printed circuit board, ensuring the best possible electrical contact.In terms of applications, the SK220M016ST is typically used in AC systems, such as switching power supplies and other circuit parts. It can also be used in DC circuits, such as when dealing with power conditioning and energy storage. Depending on the nature of the application, the capacitor could be used for energy storage and/or power filtering.The working principle of an aluminum electrolytic capacitor is based on the capacitance of a dielectric material. When a voltage is applied across two metallic plates separated by a dielectric material, the plates get polarized and the electrostatic field creates a potential difference between the plates. This potential difference is stored in the capacitor as electric energy. The distance between the plates and the dielectric material will determine the capacitance of the capacitor.In the case of the SK220M016ST, it is an aluminum electrolytic capacitor, meaning it has an electrolyte as a dielectric. The electrolyte is a chemical solution that contains both a positive and a negative charge. When a voltage is applied to the plates, the positive and negative charges of the electrolyte create a reverse-current which polarizes the plates and increases the capacitance. This voltage increases with time, resulting in more charge being held by the electrolyte, further increasing the capacitance.The charge stored in the capacitor is determined by the amount of dielectric material and their proximity to each other. The closer the plates are to each other, the higher the capacitance. This is why capacitors come in a variety of sizes and capacitances. The SK220M016ST is designed to offer a capacitance of 220 µF, allowing for adequate capacitance in a variety of applications.In summary, the SK220M016ST is a radial lead type aluminum electrolytic capacitor. It has a rated voltage of 16V and rated capacitance of 220 µF. Its low dissipation factor, low maximum capacitance error and frequency constant (16KHz) make it suitable for AC and DC applications. Its small size and lightweight makes it easy to integrate into the circuit design and its radial lead structure ensures a strong electrical connection to the printed circuit board.
