The KEMET Organic Capacitor (KO-CAP) is a solid electrolytic capacitor with a conductive polymer cathode capable of delivering very low ESR and improved capacitance retention at high frequencies. KO-CAP combines the low ESR of multilayer ceramic, the high capacitance of Aluminium electrolytic, and the volumetric efficiency.

B, C, and D failure rates available
100% accelerated steady state aging
High frequency capacitance retention
Improved humidity capability 85°C/85% RH, 1.0 VR (in black colour epoxy) available
Very low ESR values down to 5 mΩ
Surge current testing options
Volumetrically efficient

KEMET's KO-CAP Reliability Assessment method
Applications
Typical applications include decoupling , filtering and hold-up in defense and aerospace applications that require low ESR or a benign failure mode.
