Tantalum Capacitors

Tantalum capacitors are one of the most common components used in modern circuit design. The TR3D686K016C0100 is a rare example of a tantalum electrolytic capacitor, specialized for use in extreme conditions.

Application Field

The TR3D686K016C0100 is a “smaller” type of tantalum capacitor, with a voltage rating of 6.3volts and a maximum ripple current rating of 9.0A. Its small size makes it ideal for use in tight spaces and, due to the construction of the capacitor, it can be used in temperatures reaching up to 125°C and for up to 21 thousand hours without failure. These extreme conditions, along with its low ESR, make it perfect for applications in power conversion, filter networks, LED lighting, automotive, computing, telecoms and industrial.

Working Principle

Tantalum capacitors use a solid layer of tantalum oxide deposited on a tantalum metal electrode as an insulating dielectric – this layer greatly reduces leakage current and acts as a barrier to ion migration. The two electrodes are connected to the mounting plate of the capacitor and an electrolyte liquid is inserted in between them. When a current is applied, the electrolyte breaks down the tantalum oxide barrier which allows current to flow between the electrodes. This process of electrolysis is what gives the capacitor its electrical storage capabilities.

Conclusion

The TR3D686K016C0100 is a specialised type of tantalum capacitor designed for use in extreme conditions. Its small size and resistance to high temperatures make it well suited for a range of applications. Furthermore, its construction allows it to operate with very low ESR, making it an excellent choice for usage in power conversion and filter networks.
