Tantalum-Polymer capacitors are capacitor components that combine a tantalum anode with a solid polymer electrolyte. Similar to ceramic capacitors, they are most commonly used in power supply circuitry and the energy storage and filtering of a wide range of DC voltage applications. This article will discuss the application field and working principle of the T540B107K003AH85107610 tantalum-polymer capacitor.

Structure and Construction

The T540B107K003AH85107610 tantalum-polymer capacitor is composed of a tantalum anode, conductive polymer electrolyte, and solid aluminum cathode. The feature that distinguishes it from other capacitors is the use of a solid polymer for the electrolyte. This solid polymer is relatively inert and does not contain any volatile components. The anode and cathode are both constructed of sheets of metal foil, which are rolled up and held together by high-temperature, hermetic sealing techniques.

Working Principle

Tantalum-polymer capacitors work on the same general principle as a ceramic capacitor, except that instead of an oxide-based solid electrolyte, they use a solid polymer electrolyte. In a fully charged state, the capacitor consists of a positive tantalum anode and a negative aluminum cathode separated by their respective electrolytes. When a voltage is applied to the capacitor, it stores the electrical charge and acts as an energy store for future use. The net result is a very low impedance path for alternating current, which is why these capacitors are ideally suited for applications that require filtering and energy storage.

Application Field

The T540B107K003AH85107610 tantalum-polymer capacitor is typically used in applications such as power supply filtering, decoupling, and energy storage. It has a wide temperature range, from -55°C to +85°C, and can handle a range of DC voltages from 4.5V to 25V. As well, the T540 can operate with very low leakage current and is ideal for applications with high RF noise. This makes it suitable for applications such as decoupling and filtering in industrial, automotive, and aerospace controllers and systems.

Advantages of Tantalum-Polymer Capacitors

Tantalum-polymer capacitors offer many advantages compared to standard ceramic capacitors. They offer higher energy storage capacity, more efficient energy storage, and higher frequency filtering. They also require less board space, making them an attractive option for applications where board space is a major issue. In addition, their construction makes them highly resistant to thermal and shock damage, making them much more reliable and robust for high-shock applications such as automotive and aerospace.

Conclusion

The T540B107K003AH85107610 tantalum-polymer capacitor is a reliable and highly efficient energy storage device, making it ideal for a wide range of applications. By combining a tantalum anode, conductive polymer electrolyte, and solid aluminum cathode, they offer superior performance and reliability. As well, with a wide temperature range, low leakage current, and small form factor, they are an attractive option for a variety of applications, including power supply filtering, decoupling, and energy storage.
