T520V337M004ASE040 capacitor is a type of tantalum capacitor, which offers a wide range of advantages in different applications. Tantalum is a naturally occurring element that is used in the manufacture of capacitors because of its special properties. As the name suggests,Tantalum polymer capacitors are used when considerable voltage levels need to be controlled and when physical size needs to be kept minimal. These components provide extremely stable capacitance, low parasitic capacitance and reliable performance in extreme temperatures.

Application Field

Tantalum polymer capacitors can be used in a variety of applications including medical and military electronics, power supplies, signal integrity networks and communication systems. These capacitors can also be used in automotive, digital and processor-based systems, instrumentation and nuclear power devices. In addition, they are becoming increasingly popular for automotive systems, RF energy applications and nonseparated power supplies.

The T520V337M004ASE040 capacitor offers excellent reliability for applications where high temperature and energy stability are required. This type of tantalum capacitor can be used in applications where large capacitance and low parasitic capacitance are needed. It has a high capacitance per unit volume for higher capacitance applications, which makes it suitable for portable electronic devices as well as military and aerospace electronics. The low ESR (Equivalent Series Resistance) and low impedance characteristics make it an ideal choice for high accuracy and reliability, which is especially ideal for portable medical applications.

Working Principle

The T520V337M004ASE040 tantalum capacitor employs an electrolytic method of capacitance. The capacitance of the capacitor is dependent upon the material used in the di-electric. A common material used in the dielectric is called Tantalum Pentasulfide. This material allows the dielectric to be held tightly in place and to deliver consistent capacitance with aging. A thick layer of tantalum pentasulfide is applied to the inside of the capacitor case. The polymer electrolyte is then added to the surfaces of the tantalum pentasulfide and forms a positive charge. A tantalum negative foil is then added to the negative electrode and the capacitor is charged using a direct current (DC) source. The current causes ions to move from the negative electrode to the positive electrode, which generates the capacitance. Thus, when a voltage is applied to the capacitor, the polymer electrolyte is polarized and the capacitor stores electrical energy.

The T520V337M004ASE040 capacitor has the most consistent operating temperature performance among other types of tantalum capacitors. The temperature coefficient of the C-V value is extremely low, and it offers high capacitance at a stable temperature range. Additionally, the leakage current is much lower than ceramic or electrolytic capacitors. It is suitable for high-voltage DC/DC converters, AC mains line filters, switching power supply and telecommunications applications.

Conclusion

Tantalum polymer capacitors are advantageous in applications where extreme temperatures, fast line transients, and high frequency circuits are present. The T520V337M004ASE040 capacitor is an ideal choice for those applications that require high capacitance, low parasitic capacitance, and a low ESR for reliable performance. This type of capacitor offers a wide number of advantages, including high reliability and stability, low ESR and low leakage current.
