Aluminum electrolytic capacitors, also known as polarized capacitors, are some of the most commonly-used power capacitors found in a wide range of electrical and electronic devices. This article will discuss the application field and working principles of B41458B8479M000 aluminum electrolytic capacitors in detail.

1. Application Field

Aluminum electrolytic capacitors are widely applied in electrical and electronic products, such as computers, digital cameras, televisions, radios, cell phones, automotive and inverter systems. The B41458B8479M000 product is particularly suitable for power supply and equipment in industrial automation, medical, communication, automotive and other fields.

With a high capacitance density, long working life, excellent self-healing properties and a wide operating temperature range, this capacitor is suitable for filtering and precision timing circuits. Due to its robust construction and easy installation, it is often selected in harsh working environments.

2. Working Principle

B41458B8479M000 aluminum electrolytic capacitors consist of a capacitance element with two terminals, an insulating paper and an electrolyte foil. Working principle is based on the electrical double layer capacitance of electrolyte fluid, specifically, the electrolyte fluid forms a thin layer of insulation between the anode and the cathode.

The anode is made from aluminum foil which is treated to form a very thin layer of an oxide film on its surface. This oxide layer is an insulation layer, so a electric charge can be added on one side of the layer, which will also on the other side of the oxide layer to form a double electric layer. The charge decreases with distance and forms an electric field. Thus, an electrical capacitor is formed.

The electrolyte is a special liquid that is inserted into the capacitor. The anode and the cathode are immersed in the electrolyte. The electrolyte contains ions that absorbs electrical charges and generates an additional electrical field. The combination of two electric fields creates a stronger electric field, allowing B41458B8479M000 aluminum electrolytic capacitors to store more charges.

3. Conclusion

In conclusion, B41458B8479M000 aluminum electrolytic capacitors are a versatile type of power capacitor with a wide range of applications including industrial automation, medical, communication, automotive and more. With a high capacitance density, long working life, excellent self-healing properties and a wide operating temperature range the capacitor is suitable for filtering and precision timing circuits.

The principle works by the formation of an electrical double layer capacitance between two terminals, an anode and cathode, using a thin layer of oxide and an electrolytic fluid. The combination of the two electric fields from the oxide layer and the electrolytic fluid generates a stronger electric field, allowing the capacitor to store more electric charges.
