Tantalum capacitors, also known as Ta capacitors, are widely used due to their extremely high capacitance per unit volume. The TAJB156M016RNJ is one of the most popular tantalum capacitors in the market, and is widely used by electronics engineers and hobbyists alike. In this article, we will explore the application field and working principle of the TAJB156M016RNJ.

Application Field

The TAJB156M016RNJ is an axial leaded, molded and non-solid electrolytic capacitor with a size of 17.2mmx2.9mm. It is primarily used in digital circuits and battery-powered circuits due to its extremely low leakage current and excellent electrical properties. Its wide range of voltage ratings (from 4V to 35V) makes it suitable for various types of circuits and applications. It is especially useful in high-frequency circuits where its high capacitance per unit volume and low equivalent series resistance (ESR) are advantageous.

The TAJB156M016RNJ is also well-suited for use in power supplies, voltage-suppression circuits, and high-speed switching applications. Its extremely low ESR allows it to be used in noise-free circuits, and its low impedance and large capacitance give it an edge in filtering and smoothing applications. Furthermore, its high temperature tolerance allows it to be employed in applications where high temperature and vibration are present. All of these features make the TAJB156M016RNJ one of the most popular tantalum capacitors in the market.

Working Principle

The working principle of the TAJB156M016RNJ is based on the principle of electrostatic capacitor. It is made from two electrically conducting plates separated by a dielectric material. One of the plates is coated with a thin layer of tantalum metal which acts as the electric conductor. When an electric field is applied, a charge is stored on the plates. The charge stored is directly proportional to the electric field applied, and since tantalum capacitors have very thin metallic layers, they are able to store more charge than other types of capacitors.

The TAJB156M016RNJ capacitor consists of three layers - the metal plate, the dielectric material and the internal capacitor. The metal plate is made of a layer of tantalum, while the dielectric material is composed of either a ceramic or a film. The internal capacitor is filled with a solid electrolyte material, commonly manganese dioxide. The capacitor is designed in such a way that the electrolyte is held in place by an anode and a cathode. Together, these three layers form a capacitor which is capable of storing an electrical charge.

Unlike other types of capacitors, which use an air gap as the dielectric material, tantalum capacitors use manganese dioxide. This increases their capacitance per unit volume, which allows them to store larger amounts of charge and also reduces ESR. Furthermore, its ability to store an electrical charge is stable and reliable over time, making it an ideal choice for applications with constantly fluctuating electrical fields.

Conclusion

The TAJB156M016RNJ is one of the most popular and widely used tantalum capacitors in the market. It has a wide range of voltage ratings and its low leakage current, excellent electrical properties, low ESR, and high temperature tolerance make it an ideal choice for digital circuits, battery-powered circuits, power supplies, voltage-suppression circuits, and high-speed switching applications. Its unique working principle, which involves three layers of tantalum metal, dielectric material, and manganese dioxide makes it one of the most reliable and efficient capacitors available.
