Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors rely on the physical properties of anodic aluminum oxide and its ability to be polarized to function as a capacitance. The anodic oxide forms a dielectric layer between two aluminum plates, forming a capacitor. A common variety of capacitor is the wet electrolytic type, where the dielectric layer is impregnated with an electrolyte. With an applied voltage, the capacitance and voltage capability increases.

An aluminum electrolytic capacitor with model E36D351HPN471MC48M is a screw-terminal type aluminum electrolytic capacitor that is able to operate with a temperature range of -25 to +85°C and a voltage range of 105°C. It has a capacitance value of 470µF, a rated voltage of 35 V DC, and an ESR of 0.36 Ohms. It has a high voltage ripple current rating, making it suitable for a wide range of applications including high frequency power supply, switch mode power supplies, and automotive applications.

The working principle of the aluminum electrolytic capacitor is based on the Faraday Law of electrolysis. This law describes the current flow through an electrolytic solution in the presence of a voltage potential across two electrodes. The current flow produces a double layer of ions at the electrodes and produces a change in the dielectric constant of the electrolyte between the electrodes, improving the capacitance value. The electrolytic capacitance is dependent upon both the physical structure of the dielectric and the electrolyte.

The application field of the E36D351HPN471MC48M includes power supply filters, linear switching power supply, and automotive electronics such as in ECUs, fuel injection systems, and control systems as well as in UPS power systems. The capacitor can also be used in audio and video equipment, as well as in power amplifiers.
