Tantalum - Polymer Capacitors

Tantalum-polymer capacitors offer a cost effective solution for the storage of electrical charge and can be readily used in a variety of industries and applications. The T541X107M030DH8610 belongs to this range, an excellent choice due to its high reliability and affordability. Let’s now explore more information about this device including its application field and working principle.

Application Field

Tantalum-polymer capacitors are finding wide applications in the field of energy storage and conditioning, particularly in systems requiring on-board energy-dense storage. Some examples of typical applications of the T541X107M030DH8610 include in communication and military equipment, medical devices, aerospace electronics, power supplies and automotive electronics. For energy storage applications, a polymer capacitor is the choice of many due to its substantial energy-density in comparison to its lightweight profile and size. Their very low internal resistance means excellent charge/discharge characteristics and so this type of capacitor can be used as a backup power source or occasionally as the main power source. When used as an input/output filtering element, this type of capacitor provides resilient filtering and is less likely to fail in extreme temperatures as they are available in low-profile configurations. The T541X107M030DH8610 offers outstanding Electrical Overstress (EOS) protection and makes them more suitable to be placed in harsh environments.

Working Principle

Tantalum-polymer capacitors are constructed using a series of highly conductive thin layers of metal electrodes along with an ionic conductive Ta2O5 (tantalum pentoxide) layer. Ta2O5 is an oxide of tantalum and this oxide layer acts in a similar way to a battery plate in that it stores electrical charge. As the Ta2O5 layer is porous, the excess ions migrate through it which enables the capacitor to discharge the energy stored within a short amount of time.When the capacitors are connected to a voltage source, the charging process starts and the positive ions from the Ta2O5 layer move to the positive electrode, while the negative ions move to the negative electrode. The level of voltage dictates the amount of ions to migrate, thus allowing the capacitor to charge (or discharge) in a controlled manner. The T541X107M030DH8610 is constructed using two thin segmented Niobium foil electrodes and a thin perforated Polymer film separator filled with the electrolytic Ta2O5 powder. Finally, the whole unit is enclosed in a stainless steel housing.

Conclusion

The T541X107M030DH8610 is an effective and reliable type of capacitor belonging to the tantalum-polymer range. As pointed out, it offers several advantages such as its ability to store large amounts of energy as well as its robustness, making it ideal for a variety of applications including aerospace electronics, communication and military equipment, automotive electronics, medical devices or power supplies. Furthermore, its operating principle is based on the migration of electrolytic ions through the Ta2O5 layer, enabling a controlled charge/discharge operation.
