The previous characteristics show how tantalum capacitors can be uniquely suited to help in modern electronics, but they are not without their quirks and there are a couple of major ones to take into account when you want to design these in. Tantalum capacitors are generally polarized devices, meaning that during layout and assembly you need to pay more …
The result is either fewer polymer tantalum capacitors being used and a smaller footprint. The tantalum polymer capacitor is becoming the "best" solution, depending on the application and specifications. The derating differences of these three kinds of tantalum capacitors with different cathode systems will be explored in this paper.
