Tantalum capacitors are electrical components composed of a tantalum anode, a conductive electrolyte, and a cathode. They are most often used to store charge, filter signals, and reduce power losses in a variety of electronic systems. The TAP685M035CCS is one type of tantalum capacitor. In this article, we will look at the application field and working principle of this type of capacitor.

Application Field

The TAP685M035CCS is designed for specialized high-temperature, high-vibration environments which require an exceptionally robust and reliable capacitor. It has an operating temperature range of -55°C to +125°C, which is much greater than the typical operating temperature range of most tantalum capacitors. It also offers incredibly low equivalent series resistance (ESR), making it ideal for applications where low resistance or noise is critical such as in low loss AC/DC converters, switched-mode power supplies, and high current DC-DC converters.

In addition to the TAP685M035CCS’s superior temperature and resistance characteristics, it boasts low profile and high reliability contact systems which makes it ideally suited for high-density printed circuit boards and rugged environments. This makes it highly desired for application where space and vibration are a concern,such as in military and aerospace, and high-performance automotive electronics.

Working Principle

A tantalum capacitor is essentially a two-terminal, solid-state electronic component that utilizes the electrochemical properties of a tantalum anode, a conductive electrolyte, and a cathode. When a voltage is applied across the terminals, an electric current flows through the device, thereby storing and releasing electrical charges, and modifying the electrical flow.

The TAP685M035CCS follows this same basic principle, but instead of utilizing the electrochemical properties between two electrodes, it uses an anode material that is chemically stable in a high-temperature environment, with a thicker coating which stores a larger charge, and a conductive electrolyte which is corrosion resistant. This results in a capacitance that is much higher than standard tantalum capacitors and makes it suitable for very demanding operating conditions.

The TAP685M035CCS also uses a specialized contact system for mounting the capacitor to the printed circuit board. This system utilizes a low profile design and high reliability contact which helps to reduce vibration and ensures a secure connection, making the device better suited for high-vibration applications.

Conclusion

The TAP685M035CCS is an exceptional tantalum capacitor that is designed for specialized high-temperature, high-vibration environments. It has an extremely robust and reliable construction, with a low profile and high reliability contact system, and boasts low equivalent series resistance, making it ideal for applications where low resistance or noise is critical. All of these features make the TAP685M035CCS a great choice for applications in military and aerospace, and high-performance automotive electronics.
