Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in electrical and electronic circuits for a variety of purposes. They have become an integral part of modern electronics because of their airtight, low-ESR (Equivalent Series Resistance) construction, their high capacitance-to-volume ratio, their extremely high voltage ratings, and the wide range of shapes and sizes. The main application fields of aluminum electrolytic capacitors include power electronics, telecommunication, household appliances, and automotive electronics.

108CKE100MRY Application Field

The 108CKE100MRY aluminum electrolytic capacitor has a radial lead with an electrical rating of 6.3 V DC, 1000 uF, 100 μA I and 6.2 mm diameter. Its main application field is used in motor drive circuits, hybrid circuits, and high-frequency circuits. It is suitable for use in consumer, automotive, office automation, and home entertainment applications.

Working Principle of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors work on a principle similar to that of other conventional capacitors. When a voltage is applied across the positive and negative terminals, a current will flow across the capacitor. This current consists of both positive and negative charges. The positive charges move to the voltage-connected plate of the capacitor, resulting in a buildup of charge on the plate. The negative charges move to the other plate in the opposite direction, resulting in a decrease in charge.

The voltage across the capacitor is directly proportional to the amount of charge stored on the plates. When the capacitor reaches equilibrium, the amount of charge on the plates is equal and the voltage across the capacitor has reached its maximum value.As more current flows through the capacitor, more charge accumulates on the plates. This increases the voltage, resulting in a corresponding increase in capacitance. Additionally, the increase in voltage causes the polarized aluminum electrolyte to form a layer in between the capacitor plates, increasing the capacitance even further. This layer also increases the capacitance stability, allowing aluminum electrolytic capacitors to remain stable even in a wide temperature range.

Conclusion

Aluminum electrolytic capacitors are widely used in electrical and electronic circuits, with the 108CKE100MRY being ideal for use in motor drive circuits, hybrid circuits, and high-frequency circuits. The working principle involves a buildup of charge on the positive plate of the capacitor, resulting in a corresponding increase in capacitance. Additionally, the electrolyte forms a layer that further increases capacitance stability and allows for the capacitor to operate in a wide temperature range. Ultimately, aluminum electrolytic capacitors provide a reliable and effective solution for many electrical and electronic needs.
