Aluminum Electrolytic Capacitors
Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitor, is the most commonly used electronic capacitors, mainly composed of anodized aluminum foil, electrolyte, absorbent and other components. It mainly uses the principle of electrolysis, the anodic oxidation to form a porous oxide film on the surface of the aluminum foil, and the electrolyte absorbed in the pores of the oxide film forms a Helmholtz double layer for capacitance. EDH476M050S9MAA is one of the major aluminum electrolytic capacitors in its class.
Application Field
EDH476M050S9MAA aluminum electrolytic capacitors are widely used in various electronic devices, including consumer electronics, communications, industrial automation, automotive electronics, etc. Due to the limitation of volume, aluminum electrolytic capacitors are used in filtering and laying the foundation for low frequency and DC output in power circuits, especially in high power output switching power supply circuits. Moreover, they also have applications as noise filtering and coupling in audio devices, and as the power supply for ICs.
Working Principle
To better understand the inner working of EDH476M050S9MAA aluminum electrolytic capacitors, we must first have a basic understanding of the principle of electrolysis. It is fundamentally based on the fact that ions will move in an electric field, where charged ions move toward the electrodes and form a displacement current. The displacement current is formed in the direction of the electric field, and the formation of the electric field causes the displacement current of the electrolyte layer to pass through the oxide layer, thus forming the capacitance.
Every aluminum electrolytic capacitor has two electrodes, one electrode is vacuum anodized aluminum foil and the other is silicon raw material. The anodized aluminum foil has small microporous structure while the silicon has a high dielectric constant. The electrolytic capacitor works through applying cathode current to the anode, which generate positive ions and are accelerated by the electric field. The ions penetrate into the pit to form an aluminum oxide layer, and the weak base on the surface of the aluminum oxide forms a Helmholtz layer to completely cover the anode which thus forms an electrolytic layer.
When the capacitor is working, the electric field passes through the Helmholtz layer and completes the charge exchange, forming a capacitance. The size of the capacity changes with the voltage and pressure size, the greater the pressure size, the greater the capacitance. Meanwhile, the higher DC voltage should be controlled in the actual production, otherwise the capacitor itself will be damaged due to local discharge.
Moreover, anodic oxidation is essential for the application of EDH476M050S9MAA aluminum electrolytic capacitors. Anodizing is a process of electrochemical oxidation which allows the anion penetration into the metal surface forming an insulating oxide film. This oxide film determines the insulation property and the performance of the aluminum electrolytic capacitor, thus providing the necessary environment for the electrolytic capacitance.
