Moreover, in order to meet the high-efficiency demands of modern LED lighting transmitters, this particular capacitor model is also a very popular choice.

Working Principle

Aluminum electrolytic capacitors, in general, are constructed from two aluminum plates, separated by paper plates which are soaked in an electrolyte solution. Two regions of the aluminum plates are anodized, resulting in oxide layers with different thicknesses. Therefore, one of the plates will become an anode and the other will become a cathode. The contact between the oxide layers allows a significant amount of energy to be stored between them, forming an electric field.

Due to the presence of the electrolyte between the anode and the cathode, there is a significant disadvantage when using Aluminum electrolytic capacitors. This is because the electrolyte will slowly evaporate over time, reducing the capacitance of the capacitor. As a result, aluminum electrolytic capacitors have a limited lifespan, and require regular check-ups and replacements to ensure their proper functioning.

Conclusion

The B41695A188Q7 aluminum electrolytic capacitor is an excellent choice in many applications, due to its wide range of features and remarkable performance. Its application field encompasses a variety of complex designs, ranging from audio systems, LED lighting systems, to communication and industrial control systems. In terms of working principle, the capacitor is constructed from two aluminum plates, separated by an electrolytic solution. Although its presence brings some limitations, aluminum electrolytic capacitors remain a very popular choice in many markets.
