Tantalum Capacitors

Tantalum capacitors are capacitors that make use of tantalum containing an oxide-based electrolyte. They are generally small in size and have an excellent volumetric efficiency. Because of this, they are well-suited for modern, high-density electronic designs. They are also resistant to high temperatures and extremely reliable.

One of the most commonly used tantalum capacitors is the CWR26KC106MBGA/TR. This capacitor is a surface-mounted, 10µF, 16V, 25V, 35V or 50V device. It has a cylindrical, molded, two-piece construction. It also has an EIA standard size of 106M.

Application Field

Tantalum capacitors are used in a wide range of application fields including communications, automotive, industrial, medical, and defense. For example, they are used in cellphones, computers, hard drives, motor controllers, and many other electronic devices.

Due to their excellent volumetric efficiency, tantalum capacitors are ideal for high-density electronic designs. They are also preferred for designs that require an ultra-small footprint. Furthermore, they are used in high frequency designs to reduce noise and inductance. Therefore, they are used in a variety of applications, such as clock generation, energy storage, digital-to-analog conversion, RF filters, and many other signal conditioning applications.

Working Principle

A tantalum capacitor consists of two aluminum electrodes, separated by an electrolytic paste composed of a chemical known as tantalum pentoxide. One of the electrodes is in contact with the electrolyte, while the other is separated from it by a thin dielectric layer. The electrolyte serves two purposes. First, it allows electrical charge to flow between the two electrodes. Second, it acts as an insulator between the two electrodes to prevent short circuits.

When a voltage is applied to the electrodes, the electrolyte film between them begins to break down. This causes electrons to transfer from one electrode to the other, creating a small amount of electrical charge. This electrical charge is then stored in the capacitor, and can be discharged when the voltage is removed.

Tantalum capacitors are known to be very reliable and are able to withstand high temperatures. They also have a very long life cycle, as they are not prone to degradation and retain their charge well. Due to these benefits, they are widely used in many different types of electronic applications.

Conclusion

Tantalum capacitors are reliable, high-performance devices that can be used in many different types of electronic designs. The CWR26KC106MBGA/TR is a high-performance 10µF, 16V, 25V, 35V, or 50V device suitable for a wide variety of applications. As tantalum capacitors offer excellent volumetric efficiency, they are well suited for modern, high-density electronic designs. Additionally, their resistance to high temperatures and long lifespan make them an ideal choice for many high-performance applications.
