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 aluminum electrolytic and the volumetric efficiency of tantalum into a single surface mount package. Unlike liquid electrolyte-based capacitors, KO-CAP has a very long operational life and high ripple current capabilities. The T591 High Performance Automotive Grade Polymer Electrolytic delivers higher capacitance and ESR stability under harsh environmental conditions. Enhancements to the design and selected material upgrades render this the first KO-CAP capable of stable performance after 500 hours at 85°C/85% RH/VR. The T591 is manufactured in a ISO TS 16949 certified plant. Parts are available with PPAP/PSW and change control.
