Aluminum Electrolytic Capacitors are widely used in electronic circuit applications, and the B43305E2687M87 of aluminum electrolytic capacitors is no exception. In this article, the application field and working principle of the B43305E2687M87 aluminum electrolytic capacitor is discussed.

Application Field

The B43305E2687M87 aluminum electrolytic capacitor has a higher capacity and is capable of storing more energy than other types of capacitors. This makes it useful for applications such as filtering circuits, power factor control, power supply smoothing, and reset circuit noise reduction.

The B43305E2687M87 capacitor is well suited for high current applications, due to its low equivalent series resistance (ESR). This gives it low power consumption and good peak voltage surge current capacity. The low ESR also makes it particularly beneficial for applications that require high frequency noise control.

This type of capacitor is also suitable for DC/DC converters due to its high ripple current and low ESR. DC/DC converters require a capacitor that has a high capacitance and low equivalent series resistance to ensure that the converter operates with high efficiency. The B43305E2687M87 is also well-suited for input and output filter applications.

Working Principle

The B43305E2687M87 is an aluminum electrolytic capacitor, meaning that it is composed of two aluminum metal plates separated by aluminum oxide dielectric. The plates are typically metalized, meaning they are covered with a thin layer of aluminum to form an electrical contact between the surface of the plate and the electrolyte within the device. The aluminum plates are coated with manganese dioxide (MnO₂) which acts as the electrolyte. The manganese dioxide and the aluminum oxide dielectric form a capacitor.

When a voltage is applied to the capacitor, the electric current flows from the cathode (positive side) to the anode (negative side) through the manganese dioxide electrolyte. This causes a migration of the ions within the electrolyte and the Aluminum oxide of the dielectric creates a charge. This charge is held between the plates and creates an electric field, and the capacitance of the capacitor is determined by the electric field.

In addition to providing capacitance, the aluminum electrolytic capacitor also provides a low ESR, which helps with the filtering of high frequency noise, as well as improving the overall efficiency of the power converter. It is this low ESR that makes the aluminum electrolytic capacitor ideal for high current applications.

Conclusion

The B43305E2687M87 aluminum electrolytic capacitor is a popular choice for electronic circuit applications. It offers a high capacitance to store more energy than other types of capacitors, as well as a low ESR meaning that it can be used in high current applications, as well as for DC/DC converter applications. Its ability to filter high frequency noise also makes it well suitable for input and output filter applications.
