T494D476M006AT is a tantalum capacitor which combines high capacitance and volumetric efficiency. It is used in a variety of applications such as filtering, power supply bypassing, blocking and AC motor run control. This capacitor also offers several advantages including low ESR, low leakage, and excellent temperature stability.

The T494D476M006AT has a practical application range from 0.47 to 470 μF (microfarads). The capacitance value tolerance range is within ±20%, and voltage is up to 6.3 VDC. This capacitor is suitable for highly reliable applications in consumer electronics, such as mobile phones, DVD players, and digital cameras. It especially excels in the medical, military, aerospace and industrial field where reliability and performance is paramount.

The working principle of the T494D476M006AT capacitor is based on the dielectric principle. When a voltage is applied, electrons are displaced from the positive plate to the negative plate and electric charge builds up between the two plates. This charge creates an electric field between the two plates. As the electric field increases, more electrons move from the positive plate to the negative plate, thus further increasing the charge. This increase in electric charge continues until the electric field reaches the dielectric strength of the dielectric material.

The T494D476M006AT capacitor is a solid tantalum capacitor with a MnO2 layer as the dielectric material. The anode part of the capacitor contains a tantalum oxide anode and the cathode part is formed by an oxide dielectric layer. When a voltage is applied, the oxide layer is triggered to convert the ta-oxide from low conductive to a high conductive state, thus allowing charge to be transferred. With this, current begins to flow and the electric charge builds up between the two plates.

The T494D476M006AT capacitor also works as a filter to reduce high frequency noise, and provide improved signal waveforms. High frequency signals are filtered out, and what remains is a waveform with fewer noise. The capacitor is also used for energy storage in circuits. When the voltage across the capacitor exceeds its rated voltage, it can instantaneously deliver large pulses of energy.

In conclusion, the T494D476M006AT tantalum capacitor is an excellent choice for a wide variety of applications. It offers a good combination of size, reliability, and performance. It is particularly suitable for demanding applications like aerospace, medical and industrial which requires performance, reliability and temperature stability.
