Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in electronics because of their high capacitance for their size. They are also much more reliable and have a longer life than other types of capacitors. The 672D128H6R3DS5D is a type of aluminum electrolytic capacitor with a range of applications and a unique working principle.

Description

The 672D128H6R3DS5D is an aluminum electrolytic capacitor that belongs to the high voltage, low height (HVHS) family. It has a very low ESR and high ripple current ratings, making it popular in high-performance applications. It is constructed from a combination of metalized paper and metallized polyester film. The metalized paper is used for the electrodes, while the metallized polyester film is used for the dielectric and the insulation layer.

Application

The 672D128H6R3DS5D is primarily used in power electronic applications that require high-frequency operation and high-level voltage ripple operations. These applications include switching power supplies, LED lighting systems, motor driver circuits, and automotive electronics. This capacitor is also suitable for use in power systems such as DC/DC converters, high voltage rectifiers, and AC line filters.

Working Principle

The 672D128H6R3DS5D uses an electrolytic dielectric material that enables it to achieve a high level of capacitance for its size. An electrolyte solution is injected into the capacitor, forming two different layers. The first layer consists of a thin oxide layer that forms a barrier between the cathode and the electrolyte solution. The second layer is an anode contact gap that is filled with the electrolyte solution, which enables the capacitor to store charge. The charge stored in the capacitor can then be used for its intended purpose.

The metalized paper and the metallized polyester film also provide protection for the capacitor from any physical impacts or damage due to the environment. The metalized paper provides a strong, rigid outer casing, while the metallized polyester film provides additional insulation and protection from moisture, dust, and other contaminants.

Conclusion

The 672D128H6R3DS5D aluminum electrolytic capacitor is an ideal choice for applications that require high-frequency operation and high-level voltage ripple operations. It is reliable, durable, and able to provide excellent performance in a range of applications. The unique electrolytic dielectric material and the strong, rigid metalized paper and metallized polyester film provide excellent protection and performance in a range of environments.
