Aluminum electrolytic capacitors (also known as aluminum electrolytic capacitors, electrolytic capacitors, capacitors) are special capacitors, which use electrolyte solution as diaphragm and use aluminum foil with special treatment as electrodes. The electrolyte solution of the capacitor is generally ammonium borate, ammonium pentaborate or manganese chloride borate solution, which is caused by the anodically treated oxidation layer on the surface of the aluminum. The application of the 687LBB160M2DC aluminum electrolytic capacitor and its working principle will be discussed in this article.

687LBB160M2DC Working Principle

The structure of 687LBB160M2DC aluminum electrolytic capacitor is composed of an electrolyte and two metal plates fixing the slit. The two metal plates are respectively an anode and a cathode. The two metal plates, the anode and the cathode, are physically separated by a thin insulating film (diaphragm), and are electrically connected by the electrolyte in the casing. When an AC voltage is applied to the two metal plates, a certain amount of current will simultaneously flow into the electrolyte, resulting in an electric double layer at the interface of the cathode and the anode. The accumulation of electric charges generates a capacitance between the two metal plates. This is the principle of aluminum electrolytic capacitor.

The electrolyte of the 687LBB160M2DC aluminium electrolytic capacitor is an aluminum sulfate solution. When the voltage is applied to the electrolytic capacitor, an electric double layer will be formed at the surface of the anode. The aluminum electrolyte will be electrolyzed and become hydrated aluminum oxide, forming an insulator film on the surface of the anode, thus increasing the insulation strength. In this way, electrons becomes blocked and cannot flow between the anode and the cathode, forming a stable capacitance and improving the ability to withstand overvoltage.

The 687LBB160M2DC aluminum electrolytic capacitor is a special capacitor, and its capacitance and rated voltage are determined by its internal structure and electrolyte. Because of its small size, large capacitance and long service life, 687LBB160M2DC aluminium electrolytic capacitors have wide range of applications in various electronic circuits.
