Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor, which are composed of tantalum pentoxide and manganese dioxide as the dielectric layer, and an anode of the solid tantalum. Being miniature, robust and suited for high voltage applications, a tantalum capacitor has found a place in many circuits.

The TAP475M010SCS (TAP-C) is a type of tantalum capacitance, where the ‘TAP’ stands for ‘top-anode – parallel-feedback’. This capacitor is specially designed for use in military and high-end industrial applications, where vibration and temperature stability are important.

Application Field of TAP-C

The TAP-C is well suited for applications such as military navigation systems, energy management systems and telecommunications devices. Its wide range of temperature ratings (up to 125°C) makes it suitable for harsh environments, where vibration and temperature stresses occur. The wide capacitance range of the TAP-C (1μF – 180μF) also allows for flexibility in circuit design, as it can be tailored to the specific requirement of the application at hand.

Working Principle of TAP-C

TAP-C capacitors are constructed using a parallel configuration of tantalum anode and cathode layers, and a dielectric of manganese dioxide. The dielectric layer prevents electrical current from passing through the capacitor, while the thin anode and cathode layers act as the two plates of the capacitor. When a voltage is applied, the anode layer starts to absorb the charge, while the charges on the opposite cathode layer repel each other. This creates a capacitance between the two layers, which can be used to store electrical charge.

This capacitance is maintained even if the temperature changes and, in the case of the TAP-C, the capacitance changes very little when vibrating or exposed to shocks. This means that the TAP-C can accurately store and deliver the charge, which is essential in applications such as military navigation.

Conclusion

The TAP475M010SCS is a type of tantalum capacitor designed for use in military and high-end industrial applications. Its wide capacitance range, temperature ratings and high reliability makes it particularly suitable for environments where vibration, temperature and shocks are a factor. The dielectric and parallel configuration allow the capacitance to remain stable, even when the capacitor is exposed to temperature and vibration changes, making it an ideal choice for mission-critical applications.
