T491A475M016AS Capacitors

Tantalum Capacitors

Tantalum capacitors are widely used in the electronics industry due to their high insulation resistance and stability, as well as their ability to work in high temperatures. The T491A475M016AS is a type of tantalum capacitors. Its application field and working principle are summarized below.

Application field

T491A475M016AS capacitors are most suitable for industrial applications, such as in telecommunications, automotive electronics, audio systems, computers, and measuring instruments. These are also frequently deployed in DC-DC converters, DC-AC inverters, AC line filters, and wave-proof applications.

Apart from these applications, T491A475M016AS capacitors are also used in high-accuracy filters, as well as in medical and aerospace industries. Furthermore, they can be used to create high-power resistors, stable biasing, active filters, mains filters, and consumer-grade equipment.

Working principle

When a voltage is applied across the two terminals of the capacitor, an electric current will flow through its anode and cathode. This electric current will produce an electrostatic field within the dielectric material between the electrodes. As the electric current continues to flow through the capacitor, the electric charge is stored in the dielectric material, eventually building up to a voltage across the terminals.

T491A475M016AS capacitors are composed of two silver particles that are separated by a dielectric material, usually tantalum pentoxide. The anode and cathode of this tantalum capacitor are created by electrolyzing the case of the capacitor. As current flows through the capacitor, the electric charge stored in the dielectric material builds up, creating an electrostatic field within the capacitor.

The electric current then dissipates slowly as the capacitance of the capacitor decreases. The voltage across the two terminals of the capacitor remains relatively constant until all charge has been dissipated. This makes tantalum capacitors well suited for applications where the electrical characteristics must remain constant over time.

Conclusion

T491A475M016AS capacitors are popular in the electronics industry due to their ability to resist high temperatures and their high insulation resistance. These tantalum capacitors are typically used in industrial and consumer-grade equipment, as well as in high-accuracy filter circuits. When a voltage is applied to the capacitor, current flows through the capacitor, producing an electrostatic field within the dielectric material. Over time, the charge stored in the dielectric material dissipates, resulting in a constant voltage across the terminals of the capacitor.
