Solid tantalum capacitor manufacturers can make improvements in physical design and materials that reduce the overall ESR of the capacitor. These lower ESR capacitors will lead to reductions in heat generation within the capacitor, thus improving overall circuit efficiency and long-term reliability.
Two primary functions that tantalum capacitors are ideally suited for are bulk energy storage and waveform filtering. In addition to maximum working voltage and voltage derating, an important characteristic of any capacitor is its ability to store an electrical charge. Some applications require the capacitor to store large amounts of charge.
Low ESR tantalum capacitors can improve circuit power efficiency, reduce heat generation for the circuit, and increase low-term reliability. When choosing a capacitor for any application, there are a few key characteristics that must be understood in order to analyze its suitability for the circuit.
In some cases, a single tantalum capacitor is sufficient, but in more demanding applications, multiple capacitors may be configured in parallel so that their capacitance values are cumulative and the combined resistance of the array is reduced. The second factor is the ESR of the capacitors.
Tantalum and Tantalum Polymer (TaPoly) capacitors are also high CV devices, but extremely stable across temperature and voltage. Electrochemical Double Layer Capacitors (EDLC), commonly known as supercapacitors, are peerless when it comes to bulk capacitance value, easily achieving 3000F in a single element discrete capacitor.
Another advantage of using low ESR tantalum devices as bulk energy capacitors is reduced heat generation during charge / discharge cycles. This improves circuit power efficiency and results in a lower operational temperature for the circuit. It may also allow for the use of smaller power supplies for further cost savings.
