Tantalum Capacitors

T495B106K016ZTE800 Application Field and Working Principle

Tantalum capacitors are considered relatively new compared to their conventional alternatives like aluminum and ceramic capacitors, and most likely come to mind when one is talking about high capacitance within small packages. At the heart of these capacitors is a tantalum oxide dielectric, which has higher permittivity than that of either aluminum or ceramic. As such, tantalum capacitors can offer better parameters such as high capacitance, low ESR (Equivalent Series Resistance), and extended temperature range.The T495B106K016ZTE800 is an example of a tantalum capacitor and can be applied in a wide range of applications. This particular capacitor is a polar device and is best suited for higher precision circuits in the aerospace and military industries due to its high reliability and protection from aging.

Basic Structure and Working Principle

The construction of a typical tantalum capacitor can be broken down into three distinct parts: the anode, the dielectric, and the cathode. The anode is composed of a porous block of tantalum powder, while the dielectric is a tantalum oxide (Ta2O5) coat created when the anode is exposed to an oxidizing atmosphere. The cathode is composed of a layer of electrolytic material, typically a manganese dioxide (MnO2) paste formulated with a solvent. The working principle of a tantalum capacitor can be explained by examining the different components as described above. The anode provides a large surface area for energy storage, and positively charged oxyions in the tantalum oxide dielectric attracts the electrons in the electrolyte solution, creating an electrical field between the anode and the cathode. This electrical field maintains the charge and stores the energy in the capacitor as a electrostatic field, allowing it to serve as a component of a specific circuit.

Applications

Due to their high capacitance value within small packages, tantalum capacitors are used in a wide variety of applications from consumer electronics to aerospace. In consumer electronics, they are used in applications such as audio and video equipment, where high capacitance is required for large signals. They are also often used in power supplies, where it can store energy for a short period of time and release it in a controlled manner.In the military and aerospace industry, these capacitors are used to meet the strict requirements of performances such as high reliability and protection from aging. This ensures that the sensitive circuits that they help to power are able to function reliably even in extreme conditions.Finally, they are also commonly used in medical electronics, enabling the reliable operation of a wide variety of medical equipment and devices.

Conclusion

Tantalum capacitors offer a tantalum based solution for capacitors, providing higher capacitance than what aluminum or ceramic capacitors can offer. The T495B106K016ZTE800 is a particularly capable specimen of this family, and is used in a wide array of applications from consumer electronics to aerospace, due to its reliable performance and protection from aging. The working principle of the tantalum capacitor can be explained with its three main components: the anode, the tantalum oxide dielectric, and the electrolytic manganese dioxide cathode. These components combine to create an electrostatic field through the capacitor that serves to store electrical energy in a highly controlled manner, ensuring the reliable performance of the device. To sum it up, the T495B106K016ZTE800 is a particularly capable tantalum capacitor with a wide range of applications from consumer electronics to aerospace and military industries. It is highly reliable, offers high capacitance within small package sizes, and provides protection from aging. Its working principle revolves around the different components it is composed of, allowing an electrostatic field to be maintained and energy stored.
