Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as aluminum electrolyte capacitors or simply electrolytic capacitors, are electrochemical capacitors. These types of capacitors feature an aluminum oxide layer as the dielectric and an electrolytic solution as an electrode. This makes them incredibly reliable and typically much larger than other capacitor types. As such they are primarily used to store energy in high-intensity electrical systems and act as a buffer between alternating currents (AC).

ERHB5H1LGC472MFD0U Application Field and Working Principle

The ERHB5H1LGC472MFD0U is a radial aluminum electrolytic capacitor from a well-known European manufacturer. These capacitors are designed for use in applications where reliable performance, longevity and cost-effectiveness are primary considerations. These capacitors are used in the automotive electronics and white goods sector, such as cars and washing machines.

The working principle of aluminum electrolytic capacitors revolves around two processes; the formation process, and the usage process. Essentially, the electrolytic material inside the capacitor is formed by an electrical current passing through it. This current creates an oxide film on the surface of the anode, which acts as the dielectric. Due to this phenomenon, any current that passes through the capacitor experiences a voltage drop as it interacts with the oxide film.

The capacitance is determined by the size of the electrolyte, type of electrolytic material used and the voltage rating. The higher the capacitance the more real current can be passed through the capacitor before it begins to experience a voltage drop. In order to ensure reliable performance, the voltage rating of the capacitor must be higher than the voltage of the system it is being used in.

Conclusion

Aluminum electrolytic capacitors are employed in many different applications within the automotive and white goods industry due to their reliable performance and relatively lower cost. The ERHB5H1LGC472MFD0U is a particular model of aluminum electrolytic capacitor which due to its higher voltage rating is suitable for usage in high-intensity electrical systems with alternating currents.

The working principle of aluminum electrolytic capacitors is based on the formation process of an oxide film inside the capacitor, as well as the voltage drop it causes. This voltage drop is determined by the type of electrolyte, size of the electrolyte and overall voltage rating of the capacitor. The higher the capacitance, the more voltage that can be sustained by the capacitor without experiencing a drop.

In conclusion, the ERHB5H1LGC472MFD0U aluminum electrolytic capacitor is a reliable and economical choice for the automotive and white goods industry, and is useful in electrical systems which require a buffer between alternating currents. Ultimately, the capacitance and voltage rating are key considerations when it comes to choosing an electrolytic capacitor for a particular application.
