Tantalum Capacitors

Tantalum capacitors are highly advanced electronic components that are used primarily as an energy storage device in many different applications, from consumer electronics to medical devices. Most tantalum capacitors are constructed from wound-aluminum or sintered-powder almost exclusively using a tantalum anode. The solid anode and the surrounding aluminum- or sintered-powder provide the ideal conditions for a highly stable electrical charge which makes them valuable in critical applications.

The 199D685X0025C2B1 application is primarily an energy storage device as most capacitors are. It has a wide range of possible applications due to its larger size and associated features including:

• Military and aerospace.
• Portable audio equipment.
• Medical devices.
• Industrial control systems.

Tantalum capacitors are ideal for these applications due to the combination of their small size and low profile with the large capacity they offer in comparison to other capacitors. Additionally, their extremely low leakage current makes them suitable for medical applications as well as applications requiring high performance and power efficiency.

199D685X0025C2B1 Working Principle

Tantalum capacitors operate on the same basic physics principle as all other capacitors. This principle states that when opposite electrical charges are stored in close proximity, electricity is generated. Tantalum capacitors take this concept a step further by utilizing the combination of a solid tantalum anode and a highly reactive sintered-powder to provide this effect in a highly reliable and consistent manner. When a voltage potential is applied, the combination of the two materials causes a build-up of positive ions on the anode, creating an electric field that stores the energy. This stored energy can then be discharged when the voltage potential is removed and the ions will be attracted to the opposite material, allowing the energy to be released.

The more common construction method of winding a Ta-anode with an aluminum- or sintered-powder provides an even more reliable and consistent result due to the decreased risk of short and breakdown. This construction method also allows for higher maximum operating temperatures when compared to other capacitor technologies and results in a typically higher dielectric strength.

Conclusion

The 199D685X0025C2B1 is a highly advanced and reliable tantalum capacitor that is ideal for many applications due to its small size and increased capacity. Its combination of an anode constructed from solid tantalum and an aluminum- or sintered-powder provide it with the ideal conditions for a highly stable electrical charge which makes them valuable in critical applications. Additionally, its high maximum operating temperature and excellent dielectric strength make it ideal for use in the medical and military fields, as well as industrial control systems.
