Tantalum - polymer capacitors are an important component in many modern electronic circuits and devices. The TCJD477M004R0040 is an example of this type of capacitor, and is used in a wide variety of applications, from mobile phones to medical technology. It is well suited for high-frequency switching circuits and power supply circuits. This article will discuss the application field and working principle of the TCJD477M004R0040.

Overview

The TCJD477M004R0040 is a surface-mounted Electrolytic Double-Layered Polymer Tantalum capacitor. It has a capacitance of 10µF and a rated voltage of 16V. It is a small component, measuring in at 7.3mm x 4.3mm. It has a maximum capacitance tolerance of ±20%, and a maximum ESR of 0.14 ohms at 25°C.

Construction

The TCJD477M004R0040 is a double-layered polymer capacitor, meaning it contains two layers of polymer material. The first layer acts as the dielectric, and the second layer acts as the electrode. The dielectric is an electrolytic polymer film which is applied to the substrate, and the electrodes are formed from conductive parts such as aluminum, lead, or silver. These two layers are then sandwiched together, giving the capacitor its characteristic shape.

Application Field

Tantalum - polymer capacitors can be used in a variety of applications. Some of the most common application fields include automotive electronics, consumer electronics, telecoms, and medical technology. They are ideal for high-frequency switching circuits and power supply circuits, as their low ESR value makes them highly efficient.

Work Principle

When the capacitor is exposed to a voltage source, the electrostatic field generated by the voltage causes the dielectric material to polarize. This causes the electrons in the polymer material to align themselves in an orderly manner, creating an electric field. This electric field is then used to store energy within the capacitor.When the capacitor is exposed to a current source, the electric field causes the polymer material to become conductive. This allows charge to flow from one electrode to the other and allows the capacitor to act as a resistor. This allows the capacitor to act as a filter in certain circuits.

Conclusion

The TCJD477M004R0040 is a great example of a double-layered polymer tantalum capacitor. It is well suited for high-frequency switching and power supply circuits, as its low ESR value makes it highly efficient. It has a wide range of applications in consumer electronics, automotive electronics, telecoms, and medical technology. Its construction and working principle are also discussed in this article, giving readers a better understanding of this important component.
