2.Working principle of B43084A5475M aluminum electrolytic capacitor

Aluminum electrolytic capacitors are polarized capacitors, meaning that one of the electrodes is more positive than the other. The working principle of B43084A5475M aluminum electrolytic capacitor is based on the chemical mechanism. Its anode is made of aluminum foil, and a dielectric (electrically insulating) film is formed on its surface when a voltage is applied. The dielectric film is composed of two parts, which are separated by a liquid electrolyte or solid electrolyte. In this way, a certain electrical capacity is generated in the capacitor. The higher the magnitude of the applied voltage, the thicker the dielectric film generated, and the lower the equivalent series resistance of the capacitor.

When a voltage is applied, an anode current flows into the electrolytic solution to form a charge transfer process. The metal ions in the solution move towards the anode layer under the action of the electric field, thus forming a double-electron layer at the anode. During the process, new electrons are constantly supplied to the anode layer, and the capacitance of the capacitor increases.

The B43084A5475M aluminum electrolytic capacitor also contains an extended chip capacitor, which has a greater capacity and can slow down the frequency and reduce the pressure drop, providing ultra-low impedance performance, making it especially suitable for high frequency application. It has a superior ripple current and temperature coefficient that can reach 4000 hours to 10000 hours of life.

In summary, B43084A5475M aluminum electrolytic capacitor has a wide application field and reliable working principle. It can be used in precision equipments, electrical equipments, consumer electronic products and other fields. Its working principle is based on the chemical mechanism. Its anode is made of aluminum foil, and a dielectric film is formed on its surface when a voltage is applied. The electrolyte and metal ions complete a charge transfer under the action of electric field, thus achieving the purpose of electrical capacity.
