Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most widely used types of capacitors available. This type of capacitor is composed of two or more aluminum plates that are separated by an electrolyte, which is a non-conductive medium such as paper, epoxy resin, or polycarbons. It is used for storing electrical energy, providing a pathway for current, and rectifying alternating current.

ALS80C472QH500

The ALS80C472QH500 is an aluminum electrolytic capacitor from the manufacturer AVX Corporation. This capacitor is rated at 80V and has a capacitance of 470 μF in addition to a maximum ripple current rating of 0.056A, making it suitable for use in a wide range of applications.

Application Field

The ALS80C472QH500 is ideal for use in DC-DC power supplies, energy storage applications, and decoupling circuits. It can also be used in audio crossover networks and signal conditioning applications. This capacitor has good performance characteristics such as low ESR, excellent ripple handling, and stable performance over temperature.

Working Principle

The working principle of the ALS80C472QH500 is based on the formation of a double electric layer at the interface of the two aluminum electrodes. An electric charge develops at this interface, with positive charge on one electrode and negative charge on the other. This charge is stored in the capacitor as electric potential energy and is released upon demand.When an AC voltage is applied, the positive and negative charges alternate and a current flows in the capacitor, creating a feedback loop. The frequency of this current is determined by the capacitance value of the capacitor. This allows the capacitor to store energy and act as an effective low-pass filter.In addition, the capacitor can also act as a resistor in a high-frequency AC signal, providing effective decoupling and damping for the system. The capacitor helps to control the current by limiting the peak amplitude of the signal and protecting the circuits from short-term over-current.

Conclusion

The ALS80C472QH500 is a high-quality aluminum electrolytic capacitor produced by AVX Corporation. This capacitor is rated at 80V and is suitable for various DC-DC power supplies, energy storage applications, and decoupling circuits. It offers excellent performance characteristics such as low ESR, good ripple handling, and stable performance over temperature. The working principle of this capacitor is based on the formation of a double electric layer at the interface of two aluminum electrodes, which allows it to store electrical potential energy and act as an effective low-pass filter.
