Working Principle

B43504A2227M67 works based on the principles of capacitance, which involves two conductors (plates) separated by a dielectric (insulating material). When a voltage is applied between the two plates, charge is stored in the dielectric, and an electrical field is established. This electrical field creates opposing charges between the plates, creating a capacitor. When current is applied, the capacitor acts as a resistor, allowing it to filter out high frequency signals and preserving low frequency signals.

Specifically, aluminum electrolytic capacitors have two plates, one made up of a coiled aluminum foil with an oxide layer on one side, and the other made of a solid aluminum foil. The two plates are then separated by an electrolyte that is usually an aqueous solution of boric acid, sulfuric acid, and water. This electrolyte allows electrons to travel between the two plates through a process known as Faraday’s law.

As the voltage between the two plates increases, so does the capacitance. However, if the voltage increases beyond the rated working voltage of the capacitor, its breakdown voltage is exceeded, and the capacitor will fail. Therefore, good engineering practices must be used when selecting and operating aluminum electrolytic capacitors.
