Consult MoreTantalum capacitors are particularly well suited as energy storage elements in ripple filter circuits due to their low ESR. Since AC ripple is continuous and periodic, the capacitor ESR results in a continuous generation of heat as the current flows in and out of the capacitor. This is especially true in high-frequency switching supplies and ...
Consult MoreIn addition, a low ESR value allows a greater ripple current capacity to be achieved. In an aluminum electrolytic capacitor, the aluminum anode, cathode foils, electrolyte, and tabs contribute to the overall ESR of the capacitor. The value of resistance from each source mainly depends on frequency and temperature.
