Battery Back-up

Tantalum-polymer capacitors can also be used in battery back-up applications, providing an alternative to the more expensive super-capacitors. They offer an efficient and reliable way to store energy to be used in the event of a power failure.

Working Principle

Tantalum-polymer capacitors contain an anode made of tantalum powder, which is held together by a solid polymer electrolyte. This arrangement creates a high capacitance per unit volume. When a voltage is applied to the capacitor, the solid electrolyte behaves like a liquid, allowing ions to flow between the anode and cathode, forming a capacitor with a high capacitance. The capacitance of the T540D336M020DT8605 is rated at 200µF.

Conclusion

The T540D336M020DT8605 is a tantalum-polymer capacitor that offers a good balance between performance and price. Its application field includes power management, high frequency, radio frequency and battery back-up applications. Its working principle relies on its anode made of tantalum powder, held together by a solid polymer electrolyte, allowing ions to flow between the anode and the cathode to produce a high capacitance.
