Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electronic component used most commonly in power supply circuits. These components typically utilize the presence of conductive aluminum foil with an oxide coating creating a very high capacitance with very small size. This high capacitance makes aluminum electrolytic capacitors ideal for power supply applications, particularly where current is drawn over a long time frame. This article will discuss the application field and working principle of the 861141484009 aluminum electrolytic capacitor.

Application Field

The 861141484009 aluminum electrolytic capacitor is most commonly used in power supply products, AC motor drive systems, lighting technology and electronics. This capacitor is often employed in these applications because of its enhanced leakage current, lower ESR and higher temperature capabilities. Due to its higher temperature capabilities, this type of aluminum electrolytic capacitor can be used in higher temperature environments of up to +125 degrees Celsius.

The 861141484009 aluminum electrolytic capacitor is also ideal for use in LED TV/Monitor, computer notebook, and tablet applications. These systems often require a high capacitance with a high temperature. The aluminum electrolytic capacitor can provide this without compromising system performance. For example, an LED TV/Monitor of 40” or larger may require up to 20,000µF of capacitance in order to maintain signal integrity. The 861141484009 aluminum electrolytic capacitor can provide a higher capacitance for these systems, up to 35,000µF.

Working Principle

The 861141484009 aluminum electrolytic capacitor is powered solely by electrostrictive forces, and is the oldest form of capacitor. An electric field is applied in order to polarize the surface of the aluminum foil and produce a strong electrostrictive effect. This then allows for a dielectric field to form between the two surfaces, further increasing how attractive it is to use in power supply products.

The electrostrictive forces also make it easier to stack a multitude of these capacitors in order to increase the capacitance of the component. This has been possible due to the velocity of propagation, or the speed at which a signal travels through the component. This type of aluminum electrolytic capacitor has a higher velocity than other designs, allowing for the faster speeds necessary for power supply applications. This means that the 861141484009 aluminum electrolytic capacitor can provide a higher capacitance for a given size.

Conclusion

The 861141484009 aluminum electrolytic capacitor has become a popular solution for power supply applications. Its electrostrictive properties enable it to provide a higher capacitance than other types, while still maintaining its small size. Additionally, the higher velocity of propagation allows it to be more intricate, allowing for the stacking of more capacitors to increase capacitance. These features make it the ideal choice for LED TV/Monitor, computer/notebook, and tablet applications.
