Tantalum capacitor benefits and recent advances: Product how-to
The primary contributor to ESR in conventional tantalum capacitors is the use of MnO 2 as the cathode material. As shown in Figure 1, MnO 2 has a conductivity of ~0.1 S/cm. In contrast, conductive polymers, such as Poly [3,4-ethylenedioxythiophene] (PEDT), have a conductivity in the range of 100 S/cm.
These capacitors utilize a tantalum anode and tantalum case, but need a hybrid cathode made by depositing a material such as ruthenium or palladium on a small piece of tantalum foil. These large case size wet tantalums reach capacitance values of over 72,000μF at 25V and are used in energy hold-up and pulse power applications.
