It hence finds applications in power supplies, energy storage, audio/video applications, DC filtering, and switching day. It is widely used in various industries such as automotive, consumer electronics, medical, military, and industrial due to its low cost and high level of reliability.

Working Principle

The B43698A5685Q7 working principle has its roots in the Faraday’s Law of Electrolysis, which states that when an electric potential is applied across two electrodes immersed in an electrolyte, a certain amount of a chemical reaction takes place between them. This chemical reaction results in a charge exchange between the two electrodes as well as the formation of a layer of oxide/salt coating on the electrodes.The working principle of the B43698A5685Q7 capacitor then involves a series of steps that are based on this phenomenon. First, a layer of salt coating immediately forms on the electrode surfaces upon passing the electric potential. This salt coating gets deposited on the electrode surfaces, while the current continues to flow across the electrodes. This process is referred to as oxidation.Secondly, in order to create an insulating layer over the electrodes, a current passes through the oxide/salt coating. This process followed by the electrochemical reactant (battery acid) passing from the anode to the cathode through the oxide salt coating. Finally, due to electrostatic and chemical reactions, the electrode surfaces and oxide/salt coating interact and form a stable "dielectric" (insulating) film that is capable of holding charge/energy for a long period of time.

Conclusion

In conclusion, the B43698A5685Q7 aluminum electrolytic capacitor is a very useful device in modern electrical engineering due to its low loss and high capacitance. Its working principle is based on Faraday’s Law of Electrolysis, which is responsible for its superior performance in various applications such as power supplies, DC filtering, switching day, and audio/video applications.
