Tantalum Capacitors

T493C476K016CB6420 belongs to the family of tantalum capacitors. It is a type of electrolytic capacitors consisting of Ta2O5-filled tantalum anode with a porous Ta2O5 surface layer, a manganese dioxide cathode, and a polyester dielectric layer between the two plates. This capacitor exhibits high volumetric efficiency and excellent dielectric characteristics.

Application Field

T493C476K016CB6420 is mainly used for various DC electronic power supply circuit applications. It is widely used in the fields of military and aerospace, telecommunications and broadcasting, automotive, medical, and consumer electronics.T493C476K016CB6420 has excellent performance in low voltage and low temperature, has excellent high frequency characteristics, good stability, high reliability, and long life. In addition, it has low ESR and ESL, high volumetric efficiency, and excellent temperature characteristics.

Working Principle

When current passes through a T493C476K016CB6420 capacitor, positive ions migrate towards the anode, while negative ions move towards the cathode. The positive charge accumulates on the anode plate, and the accumulation increases as the current increases. At the same time, negative charges accumulate on the cathode plate, and the accumulation also increases with the increase of the current. As current passes through the capacitor, the electrical field between the two plates is built up, thus forming a dielectric with high insulation resistance.As the current reaches its peak, the amount of charge stored at each plate reaches its maximum, and the electrostatic field between them is at its maximum. As the current decreases, the electrical field diminishes. The capacitor then returns to its original state, ready to start the discharge process again.

Conclusion

T493C476K016CB6420 is a type of tantalum capacitor, mainly used for various DC electronic power supply circuit applications. It has excellent performance in low voltage and low temperature, has excellent high frequency characteristics, good stability, high reliability and long life. Its working principle is based on the accumulation of positive and negative charges on the anode plate and the cathode plate respectively, creating an electrostatic field between the two plates.
