Tantalum-Polymer capacitors are a type of surface mount capacitor developed by AvX and Vishay for use in low current applications. Specifically, T540D337M2R5DH85057280 is a single electrode tantalum-polymer capacitor with a -55°C to +125°C temperature range and a maximum capacitance of 3.3µF. Tantalum-polymers capacitors offer a high capacitance in a very small package size. Tantalum-polymer capacitors are manufactured using two sheets of plated tantalum foil electrodes that are separated by a polymer dielectric material. These capacitors differ from standard electrolytic when it comes to their size, temperature range, and cost.

The application field of T540D337M2R5DH85057280 includes but are not limited to data bus capacitance, power amplifier decay slopes and drives, signal line high frequency decoupling/bypassing, as well as filter capacitance. Furthermore, tantalum-polymer capacitors owe their unique properties to their special construction, namely the combination of the tantalum electrodes with the dielectric polymer material that can be manufactured in very small packages. This makes them ideal for applications requiring a very small form factor, such as those found in mobile phones, computers and other electronic devices.

In terms of working principle, a T540D337M2R5DH85057280 capacitor is charged by applying a voltage to its terminals. When the capacitor is connected to a DC power supply, the two plates are pulled towards each other, allowing current to flow through the capacitor and charging it up, thus storing electrical energy. When a load is applied across the capacitor’s terminals, the voltage across it will decrease and the stored energy will be discharged. The rate of energy transfer is determined by the capacitance and the rate of voltage change across the capacitor. The rate of voltage change is controlled by the equivalent series resistance (ESR) and equivalent series inductance (ESL) of the capacitor. The ESR and ESL determine the low frequency and high frequency characteristics of the capacitor.

To sum up, T540D337M2R5DH85057280 is a single electrode tantalum-polymer capacitor with a temperature range of -55°C to +125°C and a maximum capacitance of 3.3µF, designed for applications in current low applications such as data bus capacitance, power amplifier decay slopes and drives, signal line high frequency decoupling / byepassing and filter capacitance. Its working principle is based on the combination of the tantalum electrodes with the dielectric polymer material that allows for a very small form factor and very efficient working processes.
