Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of participating plate capacitor, which uses an electrolyte as one of its two plates for electricity storage. They are widely used in many electronic applications and have a range of unique characteristics that make them ideal for certain situations. This article will discuss the 63USR2200M22X40 in particular, it’s working principle, and its typical applications.

What is a 63USR2200M22X40 Aluminum Electrolytic Capacitor?

The 63USR2200M22X40 is an aluminum electrolytic capacitor with a rated capacitance of 2200 microfarads (2200µF) and a maximum operating temperature of 40°C. It has a rated voltage of 63 Volts DC, and is generally available as a radial-leaded capacitor, with leads measuring around 20mm in length.

How do Aluminum Electrolytic Capacitors Work?

The basic construction of all aluminum electrolytic capacitors is the same – two flat plates, connected by an electrolyte. The two plates are separated by a thin, permeable separator, which keeps the electrolyte from making a direct contact with the plates. In most cases, the two plates will be made out of alternating layers of aluminum foil and paper or special plastics. The electrolyte can be a solution of water and an acid, such as sulfuric acid or boric acid, or a gel-like material.

When a voltage is applied across the plates, electrons and ions move between the two plates. This causes a buildup of static electric charge and forms an electrostatic field between the two plates, storing energy within this electrostatic field. The amount of energy stored within the field depends on the size of the plates, the separator material used, and the type and concentration of the electrolyte.

Typical Applications of 63USR2200M22X40

The 63USR2200M22X40 is widely used in many electronic applications, particularly those which require frequent or sustained high power dissipation, as well as those that need non-corrosive electrolyte solutions. The 63USR2200M22X40 is commonly used as a filter capacitor in power supplies, as well as for ripple-currents in electric brush motors. It also has excellent frequency and voltage characteristics, making it ideal for use in voltage-controlled oscillators and RF/amplification systems. Additionally, it is suitable for use in applications that require very fast charging times, such as UPS and computer applications.

Conclusion

Aluminum electrolytic capacitors, such as the 63USR2200M22X40, are useful for a variety of applications due to their high capacitance and low leakage. They are also non-corrosive and have excellent frequency and voltage characteristics, making them suitable for use in many types of applications. Their ability to store large amounts of energy, and their ability to charge and discharge quickly, make them invaluable components for applications that require sustained high-power dissipation or very fast charge/discharge times.
