Abstract :
Reducing ESR in the tantalum capacitor has been the key driver in the application of polymer as a replacement for the MnO2 cathode material. Expanding this material into aluminum capacitors where the polymer replaces the wet electrolyte, not only creates another low ESR device, but introduces the aluminum capacitor to full surface mount capability
