Tantalum capacitors are used in a wide range of electronic applications, such as computer boards, power supplies, audio systems, automotive electronics, communications equipment, light fixtures, and more. The F951D106MAQ2 is a surface mount Electrolytic Tantalum capacitor specifically designed for high temperature applications. Despite its small size and simple construction, the unit provides an incredibly reliable and cost-effective solution for components that require even greater levels of performance.

Design and Constructing

The F951D106MAQ2 capacitor is a standard surface-mount tantalum capacitor, with a one-piece metallic enclosure and the tantalum anode electrolyte in the solderable copper plates connected across the capacitor terminals. The electolyte solutions are filled in the anode, and a dielectric oxide coating is formed on the anode. This oxide layer is a key factor that determines the electrical parameters of the capacitor. The positive terminal is connected to the anode, while the negative terminal is connected to the case and can serve as the ground. Solderable copper plates are connected across the terminals, which enhances the ability of the device to absorb and dissipate heat.

Operating Principle

Tantalum capacitors function on the same physics principles as standard electrolytic capacitors. When the power supply is switched on, a voltage is applied across the electrodes with a DC source, which causes an electric current to flow through the electrolyte. This electric current causes an electrochemical reaction at the anode, creating a thin layer of material that acts as an insulator from the electrolyte. This insulating layer, called the dielectric, has the ability to block current from one side to the other, allowing for the capacitor to store an electrical charge. At the same time, this layer can resist heat and dissipation, thereby providing a stable and reliable performance.

Application Field

The F951D106MAQ2 capacitor is a surface-mount tantalum capacitor, with a one-piece metallic enclosure and the tantalum anode electrolyte in the solderable copper plates connected across the capacitor terminals. The capacitor is particularly suited for applications in high-temperature and low-temperature environments, where standard aluminum electrolytic capacitors are not appropriate. It is often used as a power supply capacitor in military, aviation, and aerospace applications, as they are subjected to large temperature swings during operation and must therefore be able to handle these extreme conditions. The capacitor is also suitable for use in high-performance medical imaging systems, such as MRI scanners, as the large temperature swings associated with this type of equipment require reliable and high-performance power supply components. It is also well-suited for use in audio/VSR systems, as the smooth power delivery associated with this type of capacitor is perfect for high-fidelity audio signals.

Conclusion

The F951D106MAQ2 capacitor is a highly reliable and effective solution for applications that require high-temperature and low-temperature performance. With its one-piece construction and advanced design, the unit is virtually immune to environmental influences and can provide stable, consistent operation even in extreme conditions. Its proven performance makes it an excellent choice for use in military, aerospace, medical imaging, and audio/VSR applications. It is therefore a great choice for anyone looking for a reliable and cost-effective electrolytic capacitor.
