Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitor that uses tantalum as the anode, usually in combination with a manganese dioxide cathode. The dielectric layer is formed typically by an oxide layer of the tantalum electrolyte surface. Taxalum capacitors offer advantages such as high capacitance, very low ESR and excellent reliability.

F931E106KBA Application Field and Working Principle

The F931E106KBA is a tantalum wet electrolytic capacitor that is designed for use in mobile phones, GPS systems and other mobile communication devices. The F931E106KBA is a through-hole component that is composed of a tantalum anode and a manganese dioxide dielectric. The anode is composed of a sintered tantalum powder, which is surrounded by a conductive coating of tantalum pentoxide. The dielectric is formed by a thin layer of manganese dioxide, which is deposited onto the surface of the anode and acts as a dielectric layer. This thin layer of manganese dioxide is responsible for the capacitance of the F931E106KBA.

The working principle of the F931E106KBA is simple but effective. When an electrical current is applied to the F931E106KBA, positively charged electrons are attracted to the manganese dioxide dielectric layer, forming a layer of electrons on the surface of the dielectric. At the same time, negatively charged ions are attracted to the surface of the tantalum anode, forming a layer of positive ions. This creates a capacitor, with the positive and negative layers of electrons and ions stored in a balance. The capacitance is determined by the voltage applied to the device and the thickness of the dielectric layer.

The F931E106KBA offers a variety of advantages in the mobile communication devices. It is relatively small in size, making it ideal for devices such as mobile phones, where space is a premium. Its high capacitance makes it suitable for use in high-frequency circuits, such as mobile phones, where very small components are needed to achieve the desired frequency range. In addition, its low ESR and excellent reliability make it a reliable component for use in long-term applications such as GPS systems.

Overall, the F931E106KBA is a high-performance tantalum electrolytic capacitor that is designed for use in mobile communication devices. It offers a number of advantages such as high capacitance, very low ESR and excellent reliability. This makes it an ideal choice for use in a variety of applications.
