Tantalum - Polymer Capacitors

Tantalum - Polymer capacitors, also known as polymer electrolytic capacitors, are a type of electrolytic capacitors that uses a tantalum metal manganese dioxide-based (Ta/ MnO2) electrolytic system employing a high surface area carbon cathode and a conductive polymer anode. This type of capacitor is reliable and has the longest life of all. They are used in a variety of applications including in laptops, cell phones, hard disks and automobiles.

T540D227K004AH8505WAFL application field and working principle

The T540D227K004AH8505WAFL tantalum - polymer capacitor is designed for use in medical and industrial applications. The capacitor features high reliability and is designed to meet the requirements of medical and industrial applications. It is a low-profile and low-ESR (equivalent series resistance) capacitor and can be mounted on boards with limited heights.

The working principle of the T540D227K004AH8505WAFL is based on the principle of electrochemical capacitance. In this type of capacitor, an electrolyte and a dielectric medium are sandwiched between two electrodes. When a voltage is applied to the electrodes, the electrolyte ionizes and forms an electrolytic film, which acts as a dielectric medium. This increases the capacitance of the device, and thus enables it to store an electrical charge. The electrical charges on the electrodes form the electrical field across the dielectric medium, thus providing a storage of energy.

Characteristics

The T540D227K004AH8505WAFL has several advantages when compared to other types of capacitors:

• It has very low ESR (Equivalent Series Resistance). Most standard tantalum capacitors have ESRs of 10-50 m ohms compared to theT540D227K004AH8505WAFL’s ESR of 5 m ohms.
• It has higher capacitance compared to standard tantalum capacitors.
• It has a much lower profile, allowing it to be used in more space-constrained applications.
• It has high reliability due to its conformal coating.
• It has very low leakage current.
• It is RoHS compliant.

Conclusion

The T540D227K004AH8505WAFL is a reliable and high-performance tantalum - polymer capacitor for both medical and industrial applications. It has much lower ESR and higher capacitance compared to standard tantalum capacitors, and its conformal coating provides high reliability and excellent moisture resistance.
