Tantalum Capacitors

Tantalum capacitors, sometimes known as tantalum electrolytic capacitors, are components used for storing electric charge and providing power in electronic gadgets. The designation assigned to them, such as 173D155X9035VWE3, is based on components of the capacitor and its voltage rating; in order to understand the importance of a more specific capacitor, it is important to understand how it functions and how it fits in with a larger circuit design.

Construction

Tantalum capacitors are composed of an anode, a solid electrolyte and a cathode, which are all present in one package. The electrolyte is a conductive paste that forms the dielectric. The anode, the positive element of the capacitor, is made from sintered tantalum powder. The cathode, the negative element of the capacitor, is made from a thicker sintered material and includes a porous outer surface that contains a special contact paste containing manganese dioxide. These electrodes are separated by an anode shield, an important part of the capacitor, made from a solid plastic material.

173D155X9035VWE3 Application Field and Working Principle

The 173D155X9035VWE3 designation signifies a particular type of tantalum capacitor. It is a surface-mount device available in three voltages, 6.3V, 10V and 25V; it is also polarity sensitive and available in a variety of capacitances, from 0.001uF to 220uF. Used in automotive, industrial and telecommunications applications, the tantalum capacitor provides high levels of efficiency and excellent reliability, enabling long service life.

Tantalum capacitors work by using the dielectric material, made up of a porous anode and a solid electrolyte, to store electric charge. The anode and cathode act as a barrier which limits current flow, ensuring that the necessary current is supplied over the correct amount of time. The anode shield is then used to protect the capacitor against electric discharge and to dissipate heat. The electrolyte helps to reduce electrical noise and maintain an even voltage supply.

Examples

Surface mount tantalum capacitors of the 173D155X9035VWE3 variety are becoming increasingly popular in a variety of applications due to their characteristics. They are excellent for use in battery management systems, such as those found in electric cars, due to their ability to withstand large voltage swings and long-term storage. Additionally, they have a higher level of reliability and can be used in applications which require a steady supply of power, such as medical devices or test bench equipment. Finally, these capacitors are used to reduce system noise in telecommunications systems.

Conclusion

The 173D155X9035VWE3 type tantalum capacitor provides engineers with a reliable and compact way of efficiently storing and supplying the necessary current needed in their circuit designs. Its anode and cathode make up the dielectric and its solid electrolyte ensures continuity of electric current.
