Introduction to Tantalum Capacitors

Tantalum capacitors are electronic components made up of a tantalum metal oxide core surrounded by an anode and a cathode, usually composed of either manganese dioxide or metal oxides. Tantalum capacitors are often employed in DC power supplies, radio transmitters and communications systems, lithium-ion battery protection circuits, medical devices, and other high-power applications.

Types of Capacitors

Tantalum capacitors can be divided into two main categories: the wet-type tantalum capacitor and the solid tantalum capacitor. The wet-type capacitor has a tantalum core, which is camouflaged between separate electrolyte and anode layers. The electrolyte layer is typically a potassium hydroxide or other electrolyte solution, while the anode layer is typically manganese dioxide or a metal oxide. This design is used to increase the capacitance of the capacitor, while also providing a more reliable performance.The solid tantalum capacitor is more robust and durable than the wet-type capacitor, making it the ideal choice for applications involving harsher environmental conditions. Solid tantalum capacitors contain a sintered tantalum body filled with a high-temperature, non-conductive oxide dielectric. The capacitance of the solid tantalum capacitor is usually lower than that of the wet-type capacitor, but this is offset by the capacitor\'s overall ruggedness and reliability.

T495C475K025ATE530 Application

The T495C475K025ATE530 is a wet tantalum capacitor, and due to its design is commonly used in high-power systems that require reliable performance in conditions of extended wear, such as applications in aerospace or military systems. This capacitor features a high capacitance of 470 µF, a maximum working voltage of 25VDC, and a tolerance of +20/-40%. The T495C475K025ATE530 is a great choice for applications that need reliable power and performance in even the most adverse conditions.

Working Principle of Tantalum Capacitors

Tantalum capacitors work similarly to traditional electrolytic capacitors, in that they contain an anode and a cathode separated by an oxide layer. The oxide layer (also known as the dielectric) serves to create an electrical barrier between the two electrodes, allowing the capacitor to store an electrical charge. When a voltage is applied across the capacitor, an electric field is created, which causes electric current to flow between the anode and cathode.The electric current causes ions to be released from the tantalum metal oxide, which then migrate to the anode and become neutralized. This creates a neutral electric field across the capacitor, which causes charge to be stored on the anode and cathode. This charge continues to build up until the capacitor reaches its maximum capacitance, at which point current is completely blocked and no further charge can be stored. The amount of charge stored on the capacitor depends on the voltage and size of the capacitor and the capacitance of the dielectric.

Conclusion

T495C475K025ATE530 is a wet tantalum capacitor, with a high capacitance of 470 µF and a maximum working voltage of 25VDC. It is commonly used in high-power applications that demand reliable performance, such as in aerospace or military systems. The working principle of tantalum capacitors follows the same principle as electrolytic capacitors, in that they contain an anode and a cathode separated by an oxide layer, allowing them to store electrical charge. Through this article, we gain a better understanding of the application field and working principle of T495C475K025ATE530, as well as a general understanding of tantalum capacitors and their uses.
