Aluminum Electrolytic Capacitors – M39018/04-0053 Application Field and Working Principle

Aluminum electrolytic capacitors (known as “on kind capacitors” or “rectifier capacitors”) are a type of capacitor that utilizes an electrolyte – typically a solution of water and an electrolyte salt (saline) – to store energy and are the most commonly used capacitor type today. All aluminum electrolytic capacitors use two electrodes or plates: a positive (anode) plate and a negative (cathode) plate. The aluminum electrolytic capacitors are categorized based on the voltage rating, performance, size, and specific application.

M39018/04-0053 aluminum electrolytic capacitors are a type of aluminum capacitor that provide the longest life, highest capacitance, and highest voltage ratings among all aluminum capacitors. The M39018/04-0053 aluminum electrolytic capacitors also have a high heat and vibration resistance that makes them suitable for use in harsh or extreme environments.

Application Fields

The M39018/04-0053 aluminum electrolytic capacitors are especially known for having an extremely high capacitor voltage rating. This high rating makes them suitable for use in high voltage and high current environments such as power converters, engine management systems, power supplies, and motor control circuits. These capacitors have a capacitance of up to 3 uF and a voltage rating up to 450 volts.

In addition to their usage in high voltage and high current applications, the M39018/04-0053 aluminum electrolytic capacitors are also used in other applications such as motors, amplifiers, and switching power supplies. They are particularly suited for applications that require robust capacitors with a high capacitance and voltage ratings.

Working Principle

The working principle of the M39018/04-0053 aluminum electrolytic capacitors is based on the principle of electrolytic capacitance. In an electrolytic capacitor, electrolyte, typically a mixture of water and an electrolyte salt (saline), is stored between two plates. The positive plate is the anode and the negative plate is the cathode. A metal separator usually made of a film or sheets of aluminum, separates the two plates and serves as an insulator.

When an electric current passes through the electrolyte, the electrolyte ionizes and a thin layer of oxide is formed on the positive plate, which acts as an insulator and a dielectric. This creates a charge separation between the two plates, and an electric field is generated between them, symbolizing the capacitance of the capacitor. The larger the capacitance, the higher the electric field created between the plates.

Moreover, due to the nature of the electrolyte and metal separator, the M39018/04-0053 aluminum electrolytic capacitor also has a higher heat and vibration resistance, allowing it to operate reliably in extreme environments.

Conclusion

The M39018/04-0053 aluminum electrolytic capacitors are a type of aluminum capacitor with extremely high voltage and capacitance ratings. Due to their long life, high capacitance, and high voltage rating, they are particularly suited for use in high voltage and high current applications such as power converters, engine management systems, power supplies, and motor control circuits. Furthermore, due to their robust construction and high heat and vibration resistance, they are also suitable for use in other applications such as motors, amplifiers, and switching power supplies.
