Tantalum - Polymer Capacitors

Tantalum - Polymer capacitors are a special type of capacitor utilized in a variety of technological applications. They are a combination of a metal oxide and a polymer, with the outer metal oxide layer providing mechanical stability while allowing flexibility in the form factor and offering a low mass. The polymer layer acts as an electrode, allowing for the development of high capacitance values in reduced dimensions. The unique design and robust construction of the T540D337K006AH8510WAFL (T540D) capacitor make it a suitable choice for a wide range of applications.

Overview of the T540D

The T540D is an axial capacitor featuring an extended length design of 15.888mm and a width of 6.2mm. It is an aluminum electrolytic capacitor with an endurance rating of 2000 hours at 105°C, making it suitable for long-term use in the most demanding environments. It has a rated voltage of 10V, a capacitance of 0.0013F and a maximum ripple current of 150mA. The T540D also has a low typical effective series resistance of 0.004 ohms, and an ultra-low self-inductance of 0.0012 microhenries, making it ideal for both isolated and high-frequency applications.

Application Fields

The T540D provides a rugged and reliable solution in a variety of applications. Its combination of extreme capacitance and low series resistance make it ideal for use in pulse power and energy storage systems. It is also frequently used in power amplifier designs due to the low inductance and the extended length design. Additionally, its extended length construction is well suited for high integrity, high-temperature noise suppression circuits and interference suppression in DC/DC converters, audio and video systems.

Working Principle

Tantalum capacitors, such as the T540D, operate on the same principle as aluminum electrolytic capacitors. Electrons move from one side of the capacitor to the other by passing through an electrolyte, typically an aqueous solution. When a positive charge is present on the positive terminal, electrons move from the negative terminal through the electrolyte, creating a field. This field then attracts electrons to the opposite side of the capacitor, and the dielectric material in the capacitor prevents electrons from passing through. This creates a charge distribution on either side of the capacitor and stores energy in the electrical field. The total capacitance of the device is determined by the size and shape of the dielectric material and the size of the opposing plates.

Conclusion

The T540D is a reliable and rugged device that is well suited for a variety of applications. Its extended length construction makes it ideal for use in power amplifiers, pulse power systems and interference suppression circuits. In addition, its low series resistance and high capacitance make it an effective solution for energy storage needs. The device is designed to operate at temperatures up to 105°C for extended periods of time, making it a suitable choice for reliable and long-lasting performance in the most demanding environments.
