Capacitors may seem simple enough, but specifying them has actually grown more complex in recent years. The reason why comes down to freedom of choice. The universe of capacitors has expanded greatly over the past few years, in large part because of capacitor designs that take advantage of advances in conductive polymers.
These advanced capacitors sometimes use conductive polymers to form the entire electrolyte; or the conductive polymers can be used in conjunction with a liquid electrolyte in a design known as a hybrid capacitor. Either way, these polymer-based capacitors offer a performance edge over conventional electrolytic and ceramic capacitors. […]
The various polymer and hybrid capacitors have distinct sweet spots in terms of their ideal voltages, frequency characteristics, environmental conditions, and other application requirements. In this article, we will show you how to identify the best uses for each type of advanced capacitor. We will also highlight specific applications in which a polymer or hybrid capacitor will outperform traditional electrolytic or ceramic capacitors.
