Aluminum Electrolytic Capacitors

B43044F2226M Application Field and Working Principle

Aluminum electrolytic capacitors are electronic components that store electrical energy, usually by using a metal oxide film with a high electrical insulation as the medium and an electrolyte containing a conducting material as a counter electrode. These capacitors are widely used in a variety of electronic circuits, especially in portable computer, telecom and medical equipment. B43044F2226M is a product manufactured in Germany by EPCOS, designed for use in mobile devices and equipment that requires a very small size and light weight but high capacitance and reliability.

Application Field

As mentioned above, B43044F2226M is a miniature aluminum electrolytic capacitor intended for use in mobile devices and equipment, such as smartphones, tablets, laptops, digital cameras and portable medical equipment. Due to its small size and high capacitance, B43044F2226M is widely used in space-limited applications where size and weight is a major concern.

Working Principle

Aluminum electrolytic capacitors are built with an anode of aluminum foil and an anode of electrolyte. When voltage is applied to the terminals of the capacitor, an electrochemical reaction occurs at the anode, forming an oxide layer that has a higher dielectric constant, or permittivity. This increase in dielectric constant enables the capacitor to store a large amount of charge relative to its size, while also maintaining a low ESR. On the anode, electrolyte serves as a counter electrode and a charge-carrying medium.

When the electric field is applied to the terminals of the B43044F2226M, the capacitor stores energy by increasing the amount of electrical charge stored on the anode and decreasing the amount stored on the counter electrode. The charge stored on the anode increases with increased electric field strength, and the charge stored on the counter electrode decreases correspondingly. This cycle continues until the capacitance reaches its maximum value.

The capacitance of the B43044F2226M is also affected by the temperature of the ambient environment. In higher temperatures, the oxide layer on the anode grows thinner, which reduces the capacitance of the capacitor. Therefore, it is important to ensure that the B43044F2226M is operated in an environment where the temperature is within the recommended range, in order to maintain its capacitance.

Conclusion

The B43044F2226M is a miniature aluminum electrolytic capacitor designed for use in mobile devices and equipment. It is characterized by its small size and high capacitance, making it ideal for use in space-limited applications. The working process of the B43044F2226M involves an electrochemical reaction at the anode, which increases the dielectric constant and allows the capacitor to store a large amount of charge relative to its size. The capacitance of the B43044F2226M is also affected by the temperature of the ambient environment, and should be operated within its recommended range for optimal performance.
