Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitor that uses tantalum for its anode. These capacitors feature excellent reliability, low ESR, low leakage, and long shelf life. They are widely used in many applications, including audio and video equipment, mobile phones, computers, automotive systems, and more. In this article, we’ll discuss the application field and working principle of the T95D277K004LZSL tantalum capacitor.

Application Field

Tantalum capacitors are used in a wide range of applications for their reliable operation and long shelf life. These include power supplies, switching power supplies, dc-dc converters, computers, automotive systems, avionics, medical devices, consumer electronics, and more. The T95D277K004LZSL is a surface-mount, polymer tantalum capacitor and is ideal for surface-mount applications. Its small size allows for easier integration into design, reducing board space requirements.

Working Principle

Tantalum capacitors store energy in the dielectric formed between two electrical plates. One of these plates is made of tantalum and acts as the anode. The other plate is the cathode, which is divided into two parts: the solid manganese dioxide cathode and the conductive polymer. One side of the capacitor is the dielectric, which is typically a solid manganese dioxide film. This material has excellent dielectric constant and dielectric strength.When the capacitor is connected to a power supply, an electric field is created between the capacitor\'s plates, and the charge is stored in the dielectric material. The solid manganese dioxide acts as an insulator between the anode and the cathode, and the conductive polymer allows the electrons to flow through the cathode. When a current is applied to the capacitor, the electric field created by the anode and the cathode causes a current to flow through the dielectric, thus charging the capacitor.

Conclusion

The T95D277K004LZSL tantalum capacitors are widely used in many applications for their reliable operation and long shelf life. They feature excellent reliability, low ESR, low leakage, and long shelf life. The capacitors store energy in the dielectric between two electrical plates. When a current is applied to the capacitor, an electric field is created between the anode and the cathode, and the charge is stored in the dielectric material. The small size of the T95D277K004LZSL makes it ideal for surface-mount applications, reducing board space requirements.
