672D336H020BB5C Application Field and Working Principle

Aluminium electrolytic capacitors are widely used for their high capacitance, low cost, and long life. The 672D336H020BB5C aluminium electrolytic capacitor is a non-polarized aluminium electrolytic capacitor with a rated voltage of 20V. It has a diameter of 6.3mm and a height of 10.2mm.

This type of aluminium electrolytic capacitor is mainly used in the audio field to block DC bias, filter signal interference, and other purposes. It can also be used in other electronic equipment, such as industrial sensors and motors, telecommunications equipment, medical instruments, etc., to maintain system stability and reduce cost.

The working principle of aluminum electrolytic capacitor is based on the physical-chemical reaction between aluminum foil and electrolyte. It is mainly composed of an aluminum anode, an electrolyte absorbent paper, and a metal oxide film cathode. The anodized layer on the aluminum foil is very thin, and organic acid material is absorbed in the membrane layer to form an electrolyte, which functions as a dielectric and is the charge carrier of the capacitor. When a potential difference is applied, ions are generated due to the attraction of the terminal, resulting in charge carriers and increasing the capacitor capacitance.

Aluminum electrolytic capacitors have many advantages such as large capacitance in a relatively small size, using only one piece of equipment to achieve a certain effect, leakproof, long service life, and higher working temperature compared with other capacitors.

In conclusion, the 672D336H020BB5C aluminum electrolytic capacitor is a kind of non-polarized aluminum electrolytic capacitor with a rated voltage of 20V. It is mainly used in audio systems to block DC bias and filter signal interference, and it also can be applied to other electronic equipment. Its working principle is based on the physical-chemical reaction between aluminum foil and electrolyte. It has many advantages such as large capacitance in a small size, leakage-proof, long life and high working temperature.
