Furthermore, It can also be used in UPS, DC-DC converters, circuit breakers, HID light fixtures and spark plugs.

Working Principle

The functioning of an aluminum electrolytic capacitor is based on the Faraday Effect. In aluminum electrolytic capacitors, anodized aluminum foils are used as electrodes and they are separated by an electrolyte which acts as the dielectric. A voltage is applied between the electrodes and creates a current which creates an oxide film on the surface of the aluminum foil, thus increasing the capacitance. This oxide layer has a large electric field, which aided by the electrolyte, is responsible for the charge storage in the capacitor. When no external voltage is applied, the charges in the capacitor are stable and the capacitor has a defined capacitance.

Conclusion

The ALS30A473KE040 is a popular aluminum electrolytic capacitor that can be used in many applications. It works on the Faraday Effect, which causes an oxide film to form on the surface of the aluminum electrodes, thus creating a stable electric charge. This charge is responsible for the capacitor’s capacitance and is what allows it to be used in a variety of applications.
