KEMET's organic capacitors (KO-CAP®) are a solid electrolytic capacitor with a conductive polymer cathode capable of delivering very low ESR and improved capacitive retention at high frequencies. KO-CAP combine the low ESR of multilayer ceramic, the high capacitance of aluminum electrolytic, and the volumetric efficiency of tantalum into a single surface-mount package. Unlike liquid electrolyte-based capacitors, KO-CAP have a very long operational life and high ripple current capability.
