Tantalum (Ta) polymer capacitors are known for their stellar performance in a broad range of applications and are notably popular in space-constrained designs. The T540D337K2R5AH85057280 exemplified by the name itself is a surface-mountable Niobium (Nb) tantalum capacitor, commonly embedded in an electronic device.

Tantalum - Polymer Capacitors Overview

These tantalum capacitors are designed with a two layer anode structure, with the anode being of a tantalum (Ta) powder, and the cathode along with the anode being encased within an electrolyte, usually in the form of a solid or rubber-like polymer. These capacitors are typically smaller in size, higher in capacitance and are used in a variety of different portable applications, making them highly suitable in today’s miniature device trend.

Their architectures vary a bit and could depend on the manufacturer or device which the Ta Polymer capacitor is intended to be used in. TheTaPolymer capacitors are valued for their unique combination of attributes, which includes long life expectancy, low DC resistance, high capacitance and their ability to charge and discharge very quickly, which makes them an attractive option when needing to design a circuit.

T540D337K2R5AH85057280 Application fields and Working Principle

The T540D337K2R5AH85057280 is a miniature high-reliability, flat surface mountable tantalum polymer capacitor for use in electronics. It has Dielectric Capacitance up to 5000 μF with Operational Voltage range from 6V ~ 17V. They are designed to provide reliable performance in a variety of small, space-constrained applications, and their superior vibration and shock tolerance make them ideal for use in automotive, medical and consumer electronics, such as smartphones and tablets.

The TaPolymers operate in similar fashion to any other capacitor, by storing electric charge on their plates. The T540D337K2R5AH85057280 anode is made up of a Nb-Ta alloy with a wet tantalum electrolyte, giving it a longer shelf-life and greater tolerance for vibration and shock. The electrolyte also plays an important role in the capacitor’s electrical behavior, as its electronic conduction is responsible for providing a high capacitance with low ESR (Electric Series Resistance).

The electrolyte contained within the anode acts as a barrier to any potential leakage, so the capacitor can maintain a high reliability and stability, making it suitable for high temperature environments. Additionally, this type of capacitor offers excellent performance in terms of voltage, power and temperature calibration, as well as a low DF (Dissipation Factor) which defines the amount of power lost in each cycle.

Conclusion

The T540D337K2R5AH85057280 is an ideal choice for miniature and space-constrained applications due to its high capacitance, low ESR and excellent tolerance to vibration and shock conditions. Its two-layer anode structure with a wet tantalum electrolyte enables it to maintain a high level of electrical stability and reliability, making it one of the most popular types of tantalum polymer capacitors among manufacturers and electronic device designers.
