Tantalum capacitors are an important type of capacitor regularly found in consumer electronics, providing advantages such as low leakage current, high capacitance in a given space and a long service life in comparison to other types of capacitors. The F931C156KAA tantalum capacitor is a popular part in this family of capacitors, offering excellent performance and reliability in a variety of application fields. This article provides an overview of the F931C156KAA tantalum capacitor and its working principle.The F931C156KAA is a surface-mount tantalum capacitor with a maximum capacitance of 15µF and an operating voltage of 6.3 V DC at 85°C. It is a small, cylindrical two-terminal device featuring two anodes with a tantalum pentoxide dielectric layer between them. The F931C156KAA supports a wide range of temperatures ranging from -55°C to +105°C, making it an ideal choice for use in all types of environments including industrial, automotive and outdoor settings.The F931C156KAA tantalum capacitor is primarily used as an energy storage device, helping to smooth out fluctuations in power supply currents, reducing interference and providing a reliable power source for circuits. It is commonly used in automotive and high-power systems for decoupling or bypassing applications. It can also be employed for the filtering, buffering and integration of signals, as well as for the measurement and storage of data in electronic devices.The working principle of the F931C156KAA tantalum capacitor is based on Faraday’s Law, which states that the amount of charge stored on the capacitor’s plates is proportional to the amount of electric field applied. When a voltage is applied to the anodes of the F931C156KAA capacitor, a current is generated which causes electric charges to accumulate on the plates. This establishes an electric field between the plates, generating a capacity in which charge can be stored. The amount of electric field required to generate a certain amount of charge is determined by the dielectric constant of the capacitor’s dielectric material, which in the case of the F931C156KAA is tantalum pentoxide.In summary, the F931C156KAA tantalum capacitor is an excellent choice for a wide variety of applications, providing reliable performance and a long service life in miniature packages. It is capable of storing and releasing energy efficiently, allowing for the smooth and efficient operation of electronic devices. Its working principle is based on Faraday’s Law, and its maximum capacitance of 15µF makes it well-suited for automotive and high-power systems for decoupling or bypassing applications.
