Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor, a polarized capacitor that uses a tantalum anode and a different type of electrolytic cathode. These capacitors offer some advantages over other types of capacitors, such as lower equivalent series resistance (ESR), higher capacitance per unit volume and lower leakage current. This makes them an ideal choice for various applications.

The T491E476K035AT is a tantalum capacitor with an SMD (surface mount) package of 7343. This capacitor offers higher capacitance-voltage (CV) ratios compared to other SMD packages available on the market, and this has given it a higher popularity rating in comparison to other SMD packages.

T491E476K035AT Application Field

The T491E476K035AT is designed for applications requiring a compact and high performance capacitor. It is widely used in high-performance and high-temperature circuits, where the small size and high CV ratio are beneficial. It can be found in applications such as mobile communication, TV sets, audio equipment, radar systems, and industry control systems.

The T491E476K035AT is also used in certain space-constrained applications, such as the reduction of on-board circuitry in notebooks, LCD panel controllers, and so on. Furthermore, its small size and high CV ratio make it an ideal choice in applications such as electric vehicles and power electronics, where size and performance are important factors.

T491E476K035AT Working Principle

Tantalum capacitors work similarly to other electrolytic capacitors. However, instead of using a dielectric such as aluminum oxide, tantalum capacitors use an electrolyte sponge, which is impregnated with a solution of an electrolyte. The electrolyte solution conducts, allowing ions to move throughout the capacitor. These ions are attracted to the anode and cathode plates, forming a charge.

The construction of the T491E476K035AT is similar to other types of SMD tantalum capacitors, but its CV ratio is higher than other SMD packages. This is due to the increased surface area of the anode, which provides more "area" for ion exchange. With the increased CV ratio, the T491E476K035AT has the ability to store more charge despite its small size.

Conclusion

The T491E476K035AT tantalum capacitor is an ideal choice for applications requiring a compact and high performance capacitor. Its small size and high CV ratio make it an excellent option for space-constrained circuit applications. Furthermore, its low equivalent series resistance and low leakage current make it a reliable choice for high-performance and high-temperature circuits. With its competitive pricing, the T491E476K035AT is an ideal solution for many applications.
