Tantalum Capacitors

Tantalum capacitors are electrolytic capacitors that typically feature a tantalum metal anode, with an oxide or solid polymer electrolyte. Their major applications are in the fields of telecommunications, automotive, computers, radar, and high frequency circuits. Tantalum capacitors feature higher capacitance, higher current handling ability, and greater temperature stability than other capacitors.The F911A227KNC is a type of tantalum capacitor. It is a low-voltage, two terminal device that offers a variety of features that make it attractive for various end-use applications, such as in telecommunications, automotive, and computers. It features increased capacitance and voltage ratings as well as a high insulation resistance rating of 9000 with a 25V voltage rating.The F911A227KNC’s working principle is based on the application of the electrical double layer, which is the result of the donut-shaped electric field created by the oxide-kapton construction of the anode. This donut-shaped electric field captures and stores positive ions from the electrolyte, creating a negative charge on the electrode surface. This negative surface charge attracts positive ions from the electrolyte, which form a double layer dielectric near the surface of the anode and create the capacitor.The F911A227KNC has a lower failure rate due to its high material reliability and capacitance retention. Its low ESR and DF also reduce the temperature rise of the circuit, providing for improved performance and reliability. The F911A227KNC is capable of handling high ripple current, making it well suited for high frequency switching power supplies. Its excellent rated voltage and current capability give it the ability to meet the needs of applications that require higher voltage and current than other standard tantalum capacitors.The F911A227KNC can also be used in battery-powered applications. Its low leakage current and long-term time-constant reduce power consumption and increase battery lifetime. This makes it well suited for use in mobile phones and tablet PCs, as well as low-power designs such as Li-ion based notebooks and netbook computers.In summary, the F911A227KNC is a low-voltage, two terminal device of the tantalum capacitor family. It features increased capacitance, higher voltage ratings, higher insulation resistance and low ESR, making it suitable for a variety of applications such as in telecommunications, automotive, computers, radar, high frequency circuits, and low-power designs.
