Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, often simply referred to as electrolytic caps, are a type of capacitor that uses a layer of aluminum oxide to create an electric double layer effect when charged with a voltage. They offer a high level of capacitance and can store higher levels of energy than other capacitor types. The EKXJ401ELL181MM45S is a surface-mount aluminum electrolytic capacitor with a capacitance value of 180µF and a maximum operating voltage of 65VDC.

The Working Principle of Aluminum Electrolytic Capacitors

The working principle of an aluminum electrolytic capacitor is based on electrolytic polarization. This phenomenon occurs when an electric field is applied across two layers that are separated by an electrolyte. When an electric charge is applied, the ions within the electrolyte move in response to the electric field, causing the layers to become separated and creating the electric double layer effect.With an aluminum electrolytic capacitor, the electric double layer effect is created between an anode made of aluminum foil and a cathode made of aluminum oxides. The presence of ions around the cathode produces a negative charge, while the presence of ions around the anode produces a positive charge. This layer of negative and positive charges creates a strong electrostatic field, which can be used to store an electrical charge.
