Tantalum - Polymer Capacitors and T541X337K016AH8620

Tantalum – Polymer capacitors are becoming increasingly popular in the electronics industry due to their strong performance in demanding applications. The T541X337K016AH8620 is a high performing general purpose tantalum-polymer capacitor that combines the benefits of both materials, offering excellent stability and reliability.

What are Tantalum – Polymer Capacitors?

Tantalum-Polymer capacitors are a blend of traditional electrolytic capacitors and the latest innovations in polymer technology. They combine the excellent dielectric and electrical insulation properties of a polymer dielectric with the increasingly desirable features of a tantalum capacitor. This combination-based device has become [extremely popular for its highly reliable performance, small size, and light weight.Tantalum-polymer capacitors are constructed with a three-layer structure that consists of a cathode and anode, a polymeric dielectric layer, and a Ta2O5 (tantalum pentoxide) film. Upon application of a voltage to the capacitor, a thin film of Ta2O5 is formed on the anode terminal and serves to provide an effective dielectric layer.The unique combination of Ta2O5 and polymeric dielectrics makes tantalum-polymer capacitors suitable for high-voltage applications as well as surface-mount applications. The capacitors also offer excellent stability, reliability, and temperature performance.

Application Field and Features of T541X337K016AH8620

The T541X337K016AH8620 is a general purpose SPD-type tantalum-polymer capacitor that meets the highest standard requirements in terms of operation and safety. This capacitor is especially suitable for power supplies, UPS systems, LED drivers, medical and industrial equipment, smart meters, motor starters and heating systems, as well as for various other applications that require reliable and high-performance components. The capacitor features an excellent ripple current capability and a low temperature coefficient. It is available in various formats for leaded and surface-mount applications, and has a wide operating temperature range (-55oC to +125oC). Its low ESR, high capacitance and wide capacitance range make it an ideal choice for high-voltage applications.

Working Principle

The working principle of tantalum-polymer capacitors is based on the catalytic property of the tantalum pentoxide film. When a voltage is applied on the electrodes of the capacitor, it forms a highly conductive interaction between the electrodes and the polymeric dielectric layer. This interaction results in a depletion effect due to the polarization of the dielectric.The stimulation of electrons within the material molecules of the dielectric layer leads to a charge contribution to the electrostatic field, thus producing a capacitance. Therefore, the higher the applied field strength, the stronger the dielectric\'s polarization and the higher the capacitance.

Conclusion

Tantalum-polymer capacitors are becoming increasingly popular in the electronic industry due to their reliable performance, small size and light weight. The T541X337K016AH8620 is a high performing general-purpose tantalum-polymer capacitor that offers excellent stability and reliability. This capacitor is especially suitable for power supplies, UPS systems, LED drivers, medical and industrial systems, and various other applications requiring reliable components. The working principle of tantalum-polymer capacitors is based on the catalytic property of the tantalum pentoxide film which provides an effective dielectric layer upon application of a voltage.
