Tantalum capacitors are an indispensable component of electronic circuits and various types of electronic devices. TAJD226M025K is a popular model from the wide range of tantalum capacitors. In this article, the application field and working principle of TAJD226M025K will be discussed in detail.

Application Field

TAJD226M025K is mainly used in a variety of low power electronic circuits and digital circuit boards, such as microcontrollers, LCD displays, power converter circuits, etc. Moreover, it can be used in the power supply circuit of notebook computer. Besides, it can also be used in high frequency applications.

TAJD226M025K has the advantages of small size, high capacity and high stability. Moreover, it has very low ESR (Equivalent Series Resistance) and it also has the protection of polarity reversal and ESD (Electrostatic Discharge). All these features make TAJD226M025K suitable for various types of circuit boards.

Working Principle

TAJD226M025K consists of two electrodes, one anode, and the other is the cathode (negative). The negative electrode generally nitrogen-implantation tantalum pentoxide (Ta2O5) film, and the positive electrode is a conductive metal.

When the capacitor is in use, the electric charge passes through the capacitor, causing the current to flow along the electric field. The current flows through the anode, forming an electric field, which eventually accumulates on the cathode and creates an electrostatic field. Thus, energy and charge are stored in the capacitor.

The capacitance of a TAJD226M025K capacitor can be adjusted by its construction. The capacitance is determined by the area of the electrodes, the permittivity of the dielectric material, and the distance between the electrodes. Generally speaking, the larger the area and the closer the electrodes, the dielectric constant of the material used and the larger the capacitance.

Conclusion

In conclusion, TAJD226M025K is a popular model of tantalum capacitors, which is widely used in a variety of low power electronic circuits and digital circuit boards. Besides, it has the advantages of small size, high-capacity, high stability and low ESR. Its working principle is mainly based on the electric charge passing through the capacitor and the electric field created on the cathode.
