Kemet's Organic Capacitors (KO-CAP) are solid electrolytic capacitors with conductive polymer cathodes that provide very low ESR and improve capacitance retention at high frequencies.
Automotive grade KO-CAP capacitors combine the low ESR of multilayer ceramics, the high capacitance of aluminum electrolysis, and the volumetric efficiency of tantalum into a surface-mount package. The company said that unlike liquid electrolyte-based capacitors, KO-CAP has a very long life and high ripple current capability.
