Tantalum Capacitors

Tantalum capacitors have become the preferred choice for electronic components due to their excellent electrical and performance characteristics. Unfortunately, they still remain relatively obscure compared to other more common types of capacitors such as ceramic, electrolytic and film.

199D105X9035A6V1E3 Application Field

Tantalum capacitors are generally used in applications where high capacitance and/or robust performance is desired. A common use is decoupling capacitors for high frequency circuit noise suppression and isolating and suppressing any RF signals generated in the device. These capacitors are also popular for use in high-speed power supplies and in circuit boards where a high-voltage resistor is required. Moreover, tantalum capacitors are used in a variety of communication systems and other critical power supply applications.

199D105X9035A6V1E3 Working Principle

A tantalum capacitor is a polarized capacitance device that stores an electrical charge. It consists of a tantalum metal layer and an electrolyte material, such as a conducting polymer, housed inside a dielectric material, such as ceramic. The tantalum metal layer is the positive terminal and when an external voltage is applied, electrons will flow from the negative terminal to the tantalum metal layer. This forms an electric field within the dielectric material and creates an electrostatic charge stored in the capacitor.The capacitance of the device is determined by the combined effect of the area of the metal plate, the thickness of the dielectric material and the distance between the metal plate and the electrolyte material. The higher the capacitance, the more charge a capacitor can hold and the lower the equivalent series resistance.Additionally, tantalum capacitors possess high leakage current and are generally equipped with self-healing properties. This means that should an increase in current cause the dielectric to fail, the capacitor will immediately reduce the current down to a safe level and subsequently begin to heal itself.

Conclusion

Tantalum capacitors, such as the 199D105X9035A6V1E3, are highly versatile electronic components that are useful in a wide variety of applications. They exhibit excellent electrical characteristics and can hold a large amount of charge. Furthermore, they are equipped with self-healing properties that help maintain their integrity in the face of potentially detrimental current increases.
