Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized capacitors which utilize a formed aluminum anode electrode with an etched surface and a liquid or solid electrolyte as its cathode. It typically contains high capacitance relative to its size and relatively high cost of production. Consequently, they are mainly used in applications such as power supplies, frequency tuning, and transient suppression.

511D476M100CG4D Application Field and Working Principle

The 511D476M100CG4D Aluminum Electrolytic Capacitors are commonly used for high temperature applications due to their ability to operate at high temperatures up to 125°C. It is also distinguished by its quick and accurate DC and AC response time, making it an ideal choice for frequency tuning and transient suppression. The 511D476M100CG4D works by building a barrier between the two conducting plates, thereby creating an electrical field between them. This electrical field is proportional to the amount of charge the capacitor stores, which is determined by the amount and type of electrolytes used.

The capacitance of a 511D476M100CG4D aluminum electrolytic capacitor is primarily dependent on its material and design. The anode is usually made of rolled aluminum foil with a coating of an electrolyte and a semi-permeable membrane covering the entire surface. The electrolytes used are usually organic, alkaline or electrolyte-based, depending on the application. The cathode is typically made out of activated carbon, which increases the amount of charge that the aluminum anode can carry. The anode foil and cathode material are then assembled inside a hermetically sealed metal or plastic container to protect the capacitor from physical damage and the corrosive action of the electrolyte.

The 511D476M100CG4D is mainly used for audio frequencies, but can be used in a variety of other applications. Like all electrolytic capacitors, the 511D476M100CG4D may suffer from electrolysis and corrosion over time, which could result in a decrease in capacitance or early failure. It is therefore important to ensure that the conditions in which the capacitor is used are suitable for its expected life span.

Advantages and Disadvantages

The 511D476M100CG4D aluminum electrolytic capacitor offers a variety of advantages, including its ability to operate at higher temperatures, its accurate and quick response time, and its ability to store a high amount of charge. Additionally, the capacitor offers extremely low leakage current, making it an ideal choice for use in applications involving high performance and precision. The capacitor is also relatively easy to manufacture, as it only requires a few components and a simple assembly process.

The main disadvantage of the 511D476M100CG4D aluminum electrolytic capacitor is its relatively high cost of production, which can be a significant factor when considering which type of capacitor to use in a specific application. Additionally, the capacitor is relatively fragile and susceptible to damage from corrosion and electrolysis over time, which could dramatically decrease its capacitance or cause it to fail early.
