Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are capacitors that use an electrolytic solution of tantatic oxide (Ta2O5) as a dielectric. They are commonly used in power supplies, high-frequency circuits, and other applications that require a high capacitance-to-volume ratio. The 199D475X0016B6V1 is an example of a tantalum capacitor. This capacitor has a capacitance of 4.7uF and a rated working voltage of 6.3V, making it suitable for use in a wide range of applications.

Application Field of 199D475X0016B6V1

The 199D475X0016B6V1 is a long-life, miniaturized electrolytic capacitor with a small ESR and low equivalent series resistance (ESR), making it an ideal choice for use in power supplies and high-frequency circuits. It is also used in decoupling, DC bias, and other small signal applications. Its small size makes it suitable for use in cramped spaces, making it an excellent choice for applications where space is at a premium.

Working Principle of 199D475X0016B6V1

All capacitors store charge by having two adhesive electrodes that are separated by an insulating material, known as a dielectric. When a voltage is applied to the capacitor, current flows from one electrode to the other, creating an electric field. The voltage is divided between the electrodes and the dielectric, and the magnitude of the field created determines the amount of charge stored in the capacitor.

The 199D475X0016B6V1 uses a tantalum electrolytic solution as the dielectric, meaning that it uses an acidic electrolyte containing a large amount of dissolved tantalum ions. This solution has a much larger dielectric constant than vacuum-filled capacitors, resulting in a much greater capacitance-to-volume ratio. In addition, the tantalum ions form a protective oxide film that further increases the capacitance and improves the stability of the capacitor.

Conclusion

The 199D475X0016B6V1 is a long-life tantalum capacitor with a capacitance of 4.7uF and a rated working voltage of 6.3V. It is commonly used in power supplies, high-frequency circuits, and other applications that require a high capacitance-to-volume ratio. Its use of a tantalum electrolytic solution as a dielectric allows it to have a much greater capacitance-to-volume ratio than vacuum-filled capacitors and improved stability.
