Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are essential components in numerous electronic devices used both home and commercial. Most types can be identified by their model numbers, such as 63YXA47M6.3X11. This model is a standard aluminum electrolytic capacitor with an operating voltage of 37V, a capacitance value of 47uF, and a tolerance of +/-20%.

Application Fields

Aluminum electrolytic capacitors are extremely versatile and are commonly used in a wide variety of applications. Typical use includes power supplies, motor drives, and high-frequency circuits in consumer electronics such as TVs, stereos, and computers. Additionally, they can also be used for dc-dc converters, low-inductance filters, and decoupling of logic signals.

Working Principle

An aluminum electrolytic capacitor is constructed of two aluminum foils (the anode and the cathode) which are separated by a paper spacer coated with an electrolyte. As electrical current passes through the capacitor, an electrostatic charge builds up between the two foils, thus creating a capacitance. The capacitance value of the capacitor is proportional to the areas of the two aluminum foils and the thickness of the paper spacer.When the voltage across the capacitor exceeds its rated voltage, the electrolyte is compressed and leakage current begins to flow from the anode to the cathode. This is known as “dielectric polarization” and reduces the capacitance of the device. As the voltage is further increased, the capacitance drops further until the capacitor eventually fails.

Conclusion

Aluminum electrolytic capacitors are an important part of the modern electronics world. They are ubiquitous and can be found in numerous consumer devices and power supplies. With the widely universal model number of 63YXA47M6.3X11, the capacitor offers a wide range of uses, including power supplies, motor drives, high-frequency circuits and more. Its working principle is based on an electrostatic charge building up between two aluminum foils separated by an electrolyte-coated paper spacer. Understanding this principle is important for proper use and maintenance of these critical components in all types of electronics.
