Tantalum-Polymer capacitors, commonly referred to as Ta-Polymer capacitors, are a class of capacitor which has been growing rapidly in popularity due to its small size and relatively high capacitance. The T540D687K2R5DH86057610 is an example of such a Ta-Polymer capacitor, and has a capacitance value of 6.87µF, a high maximum operating temperature of 85°C, and is rated for an operating voltage of 16VDC. Furthermore, this particular part has a radial-leaded tantalum casing with a length of 5.6mm and a diameter of 4mm.

The most common application of Ta-Polymer capacitors is in portable electronics such as smart phones, tablets, and other hand-held devices. Ta-Polymer capacitors offer the portability that hand-held devices demand, as well as increased performance over ceramic capacitors. This particular capacitor is no exception and could be used in any number of portable electronics applications where its small size and high capacitance are beneficial.

The working principle of a Ta-Polymer capacitor is similar to that of other types of capacitors, such as aluminum electrolytic or ceramic capacitors. When electric current is introduced to the Ta-Polymer capacitor, electrons are attracted to the positive side of the electric field, while positive ions are attracted to the negative side of the electric field. This creates a positive electric field on one side of the capacitor and a negative electric field on the other. The electric field stores electrical energy which can then be released back into the circuit when needed. This process is what allows the capacitor to act as a store of charge and current in a circuit.

In addition to hand-held electronic applications, Ta-Polymer capacitors are also popular for general DC applications, such as those found in automotive, audio, and telecom applications. Their small size and high capacitance make them well-suited for these types of applications, where size and current output are of the essence. As such, the T540D687K2R5DH86057610 Ta-Polymer capacitor could be used for applications such as powering a car radio, amplifying signal in wireless systems, or even filtering out unwanted frequencies in a signal processor.

Ta-Polymer capacitors are also commonly used in high-reliability, military and aerospace applications. The high reliability of Ta-Polymer capacitors makes them ideal for applications where failure is not an option, such as in aircraft navigation systems. The T540D687K2R5DH86057610 could potentially be used in such applications thanks to its high capacitance and long life expectancy.

In summary, the T540D687K2R5DH86057610 Ta-Polymer capacitor is a relatively small device with a high capacitance, which makes it a suitable choice for many portable, DC, military and aerospace applications. Its small size, high capacitance, and long life expectancy make it ideal for applications such as powering car radios, amplifying signals in telecom systems, filtering out unwanted frequencies in signal processors, and much more.
