Furthermore, this model of capacitor is also suitable for low ESR, long-term reliability in audio circuits and frequency control.

Working Principle

Tantalum capacitors work in the same way as other dielectric capacitors. A pair of conductors (anode and cathode) are separated by a non-conducting material (dielectric). When a voltage is applied to the capacitor the dielectric reacts, allowing current to flow between the anode and cathode, which creates an electric field.

The dielectric in tantalum capacitors is a layer of tantalum pentoxide, which is formed by the anodic oxidation of a tantalum cathode. This process reduces the size of the electrical field by increasing the resistance of the dielectric, achieving greater capacitance. This increase in capacitance allows the capacitor to store greater amounts of energy, making them great for use in high performance electronics.

Conclusion

The T494D336M020AT tantalum capacitor offers outstanding performance and reliability, making it one of the best choices when it comes to providing stable capacitance for various high performance applications. Its low ESR and high temperature range make it perfect for space and audio applications, while its high current rating makes it the ideal choice for high power circuits.
