Aluminum electrolytic capacitors are electrolytic capacitors with a solid conductive anode. The anode is made from a highly porous aluminum layer, which is typically covered with an organic insulation material. The dielectric layer of an aluminum electrolytic capacitor is a very thin layer of aluminum oxide, formed by chemical reaction between the anode and the electrolytic solution. The electrolytic solution typically contains a dissolved electrolyte, an ionic salt, and other chemicals such as surfactants and buffers. As current flows through the electrolytic solution, electrons move from the anode, through the electrolyte, to the cathode. This creates a chemical reaction at the anode, which deposits the aluminum oxide around the anode.

The EEU-FR0J122B aluminum electrolytic capacitor is a radial-leaded axial-type capacitor designed specifically for use in audio and video applications. It uses a conductive anode consisting of a highly porous aluminum layer and has a capacitance of 100uF, a voltage rating of 250V and a tolerance of ±20%. The anode is insulated by an organic dielectric layer and the capacitor uses a conductive electrolytic solution to form an electrolytic oxide layer at the anode and thus allow for the electric current to flow. The EEU-FR0J122B is typically used for signal filtering, signal conditioning, power supply filtering and power supply decoupling in audio and video systems.

The working principle of an aluminum electrolytic capacitor is based on electrochemical reactions between the anode and the electrolyte. The anode is composed of a highly porous aluminum layer which, when current is applied to it, creates a chemical reaction that forms the aluminum oxide layer which forms the dielectric layer. This allows the current to flow through the electrolytic solution between the anode and the cathode and thus to create an electric field. This electric field creates capacitance, which is the ability of the capacitor to store electrical energy, by providing a delay in the voltage amplitude rise. This allows for signal or power conditioning such as for filtering, or for controlling the speed of a motor.

In summary, the EEU-FR0J122B aluminum electrolytic capacitor is a radial-leaded axial-type capacitor designed specifically for audio and video applications. It consists of a highly porous aluminum layer as its anode and an organic dielectric layer that provides insulation. The capacitor has a capacitance of 100uF and a voltage rating of 250V, allowing it to be used for signal filtering and power supply filtering. The working principle of an aluminum electrolytic capacitor is based on electrochemical reactions and electric field created between the anode and the electrolyte. This creates capacitance, allowing for the capacitor to store electrical energy and thus allow for signal or power conditioning.
