Tantalum capacitors, also known as tantalum electrolytic capacitors, belong to a type of electrolytic capacitors that use tantalum as the anode. The back-electrode is made of a conductive porous material that can be tin-plated, silver-plated, or sintered silver particles and stainless steel, and the electrolyte of the capacitor is an organic solvent. Most of these capacitors are molded into small boxes and sealed because they are based on a wet electrolyte system.

TH3B475K016F2100 Application Field

The TH3B475K016F2100 is a type of tantalum capacitor manufactured and produced by TDK. It is a radial leaded tantalum capacitors containing MnO2 as the oxide, with a rated capacitance of 47μF and a rated voltage of 16V. It is mainly used in communication devices, DC power input and output, bypass circuits, and decoupling circuits in high-density portable electronic products. Furthermore, it can also be used in power supply circuits, conditioning circuits, and other electronic equipment.

TH3B475K016F2100 Working Principle

The TH3B475K016F2100 working principle is based on a conventional electrolytic principle and is essentially the same as that of an aluminum electrolyte capacitor. It uses tantalum as the anode and a conductive electrolyte material as the cathode. When a voltage is applied to a pair of plates, it creates an electrolytic system and the current will pass through it. In this way, the electrical energy it stores is generated due to the electrolytic reaction. As one of the most reliable capacitor varieties, it has a wide operating voltage, excellent insulation resistance, and high capacitance. It is also able to withstand a relatively higher range of temperatures and frequencies than other capacitor types.

Advantages of Using TH3B475K016F2100

The use of the TH3B475K016F2100 capacitors offers several advantages compared to other capacitor types. The oxide layer of these capacitors is highly conductive, providing a low ESR (Equivalent Series Resistance) and excellent ripple current capability. These characteristics make them ideal for high frequency and wide temperature applications. In addition, the MnO2-based tantalum capacitor has a miniature size and a high insulation resistance, making it suitable for high-density portable electronic products. Furthermore, its reliability is also increased due to the higher capacitance and larger capacitance stability at high temperatures.

Disadvantages of Using TH3B475K016F2100

The main disadvantage of using MnO2-type tantalum capacitors is its low operating temperature. Compared to aluminum electrolytic capacitors, using higher temperature may cause irreversible damage to the oxide layer of the TH3B475K016F2100, leading to short-circuiting and capacitance decrease. It also has a lower allowable ripple current than aluminum electrolytic capacitors, so it cannot be used in circuits that require high ripple current. Finally, due to its high cost, it is used only in applications where its advantages are necessary.

Conclusion

The TH3B475K016F2100 capacitor is a type of MnO2 based tantalum capacitor that is used in various applications. It has good conductivity, offers excellent ripple current capability, and is suitable for high-density portable electronics. However, it requires lower operating temperatures than aluminum electrolytic capacitor types and its cost is higher. In conclusion, it is used only in applications where its advantages are needed.
