TRJC476K010RRJ

Tantalum Capacitors

TRJC476K010RRJ is a type of capacitors that falls under the tantalum category. It is a polarized capacitor and encompasses many advantages such as a low equivalent series resistance, low leakage current values, and is able to withstand large temperature ranges.

Application Field

The TRJC476K010RRJ is most commonly used in industrial, military, and aerospace applications due to its enhanced properties and greater performance. Its low ESR and higher capacitance enables it to be used as an energy storage capacitor in motor control and inverter applications. It is also used in "high ripple current" applications, where AC to DC converters require large ripple currents to be supplied, such as in the plasma TV and microwave oven. In addition, since it is able to achieve high pulsed power rates, it can also be applied in radar and communications.

Working Principle

The capacitor is made up of two conducting plates which are immersed in a dielectric material, also known as the electrolyte, typically an oxide. A reference voltage is applied between the two plates which creates an electric field across the dielectric material, which creates an attraction between the two plates and creates positive charges of one sign and negative charges of opposite sign on each plate. This creates an electric circuit, reducing the fluctuations and smoothing out the current supply.

The dielectric constant of the electrolyte material determines the ability of the capacitor to store charge. The TRJC476K010RRJ capacitor has a high dielectric constant, as well as low ESR, making it suitable for high current applications.

The polarized nature of the capacitor ensures that current can only flow in the correct direction. If the capacitor is reversibly connected, it may work for a short time, but eventually it will be damaged due to the excessive voltage applied by the reverse current.

Conclusion

The TRJC476K010RRJ capacitor is a type of tantalum capacitor used in a variety of applications due to its high dielectric constant, low ESR and its ability to withstand high temperatures. It is also able to achieve high pulsed power rates, and is used in radar, communication and other applications were high ripple current is required.
