Tantalum Capacitors

T496B475M010AT is an important type of tantalum capacitor. Tantalum capacitors are solid electrolytic capacitors, made of tantalum metal and containing a very thin layer of oxide across which charge can be stored.

Application Field

Tantalum capacitors are widely used in computers, mobile phones, audio equipment, and other electronic devices. The most common applications include power supplies, automotive electronics, portable/handheld electronics and audio/video equipment.

Tantalum capacitors are much smaller than other types of capacitors, and thus require very little space. Therefore, they can be used in extremely tight spaces and can be used to great advantage in the miniaturization of electronics.

Additionally, tantalum capacitors can handle high temperatures and have excellent performance at high frequencies. As such, they are often used in high frequency or high speed applications, such as in cell phones. They are also used in switching power supplies and other power converters.

Furthermore, they are often used in RF applications, as they can provide low ESR, high capacitance and high frequency performance. Additionally, they are widely used in medical and space applications, as they provide reliability and can withstand harsh environmental conditions.

Working Principle

Tantalum capacitors are similar to other types of electrolytic capacitors in that they operate on the principle of charges being stored on one dielectric material. The dielectric material used in a tantalum capacitor is a layer of tantalum oxide. The oxide is formed by depositing an anodized film of tantalum on the surface of a metallic tantalum plate.

The oxide acts as a semiconductor, allowing electrons to move freely between the two plates of the capacitor. When a voltage is applied, the oxide semi-conductor become exposed to the current, thus allowing charge to flow through, and then be stored in the oxide layer on the surface of the dielectric.

Additionally, the oxide layer acts like an insulator, preventing the leakage of electrons, and allowing for the storage of charge for extended periods of time. This allows for a much higher capacitance than other types of capacitors.

The dielectric is rated based on the ability of the capacitor to store charge, as well as its ability to withstand temperature and voltage ratings. This rating is expressed in volts, up to around 200V.

Tantalum capacitors can also be made with an organic polymer dielectric. This type of capacitor is suited for high-frequency or high-power applications. The polymer dielectric allows for increased capacitance and a lower ESR (equivalent series resistance).

Conclusion

T496B475M010AT is an important type of tantalum capacitor, and has a wide range of applications. It is extremely small and can be used in extremely tight spaces, and is capable of handling high temperatures and high frequencies. It is often used in RF applications due to its low ESR and high capacitance, as well as in medical and aerospace applications due to its reliability and its ability to withstand harsh environmental conditions.

The working principle of a tantalum capacitor is similar to that of other types of capacitors, but is unique in that it uses an oxide dielectric layer for storage of the charge. The dielectric is rated based on its ability to store charge, withstand temperature and voltage ratings. Additionally, polymer dielectric versions of the capacitor are available for high-frequency and high-power applications.
