Tantalum capacitors offer high reliability, compact size and long life, making them ideal for use in a wide range of high-frequency, low-voltage applications. The T97D476K050N8TSB is a tantalum capacitor designed to meet the needs of a variety of electronics and telecommunications applications. This article gives an overview of the application field and working principle of the T97D476K050N8TSB.

Application Field

The T97D476K050N8TSB is a professional-grade automated IC capacitor, which provides high reliability and long life in a wide range of high-frequency, low-voltage applications. Common uses include frequency control applications, surface mount applications, and military/flight applications. The capacitor is also suitable for use in many consumer electronics – including smartphones, portable gaming systems, cameras, and televisions – due to its low ESR and high ripple current capabilities. Additionally, it can be used in automotive, telecom, and audio applications, such as in the analog signal conditioning of radio and audio equipment.

Working Principle

Tantalum capacitors, in general, are types of electrolytic capacitors with an anode consisting of a porous tantalum core, which is covered with an oxide layer containing electrolytic solution. During the charging process, a voltage is applied and a small current passes through the porous tantalum core, which creates a double-layer capacitor consisting of two charge carriers, one from the electrolytic solution and one from the oxide layer of the porous anode. This develops a "pseudo" plate and the capacitor is charged with the primary current.

The T97D476K050N8TSB is a monolithic IC capacitor with an integrated circuit (IC) of the anode dielectric. The integrated circuit contains semiconductor components, which allow the capacitor to store more charge than conventional tantalum capacitors. This increases its capacitance and allows it to operate in higher power applications than conventional tantalum capacitors.

When the capacitor is discharged, the integrated circuit will also switch off the current in the capacitor and limit the voltage- current to prevent damage to the capacitor and/or surrounding device. The capacitor can also be self-regulating to ensure that the capacitor does not exceed its voltage and current ratings. The resulting protection improves reliability and extends the lifetime of the capacitor.

Conclusion

The T97D476K050N8TSB is a professional-grade automated IC capacitor, designed to meet the needs of a variety of high-frequency, low-voltage applications. It has an integrated circuit of the anode dielectric, which allows it to store more charge than conventional tantalum capacitors, and provides self-regulating protection to improve reliability and extend the lifetime of the capacitor. It is ideal for use in applications such as frequency control, surface mount applications, military/flight, automotive, telecom, and audio applications.
