In the telecom industry, they are widely used in high-frequency communication systems and mobile phones. In military applications, they are applied to electronic information equipment and communication systems.

Working Principle of UKL1E4R7MDDANA Aluminum Electrolytic Capacitors

The UKL1E4R7MDDANA aluminum electrolytic capacitor consists of a wound anode, a diaphragm, an electrolyte and a cathode terminal. These capacitors work through a process called electrolysis, which is the decomposition of an electrolyte due to the action of an electric current. The anode and cathode of UKL1E4R7MDDANA aluminum electrolytic capacitors are made of aluminum foil and are rolled up together to form an anode roll or tube. The diaphragm is an insulating film that separates the anode and cathode. When the supply voltage is applied, an electric field is created across the diaphragm and causes a displacement current to flow. The electrolyte completes the electric circuit between the anode and the cathode and enables the current flow. The dielectric film is formed as a result of the reaction between the electrolyte and the anode. This film has the ability to store a charge, thus acting as a capacitor. The stored energy creates an anodic oxide layer on the aluminum foil surface, which improves the electrolytic capacitor’s insulation properties and reduces its ESR (Equivalent Series Resistance). This layer is also referred to as an electrolyte barrier layer.

Conclusion

UKL1E4R7MDDANA aluminum electrolytic capacitors are among the most reliable and widely used type of capacitors. Due to their long life span, high energy density and low ESR, they are suitable for a wide range of applications in various industries. They work through a process called electrolysis, which is the decomposition of an electrolyte due to the action of an electric current. The anode and cathode of UKL1E4R7MDDANA aluminum electrolytic capacitors are made of aluminum foil and are rolled up together to form an anode roll/tube. The dielectric film formed as a result of the reaction between the electrolyte and the anode is able to store a charge and act as a capacitor.
