The KEMET Organic Capacitor (KO-CAP) is a solid electrolytic capacitor with a conductive polymer cathode, capable of delivering very low ESR and an improved capacitance retention at high frequencies. KO-CAP combines the low ESR of the multilayer ceramic, the high capacitance of aluminium 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/T598/T599 High Humidity and High Temperature Polymer Electrolytic capacitors deliver higher capacitance and ESR stability under harsh environmental conditions. Enhancements to the design and selected material upgrades were introduced to deliver 500 hours (T591) or 1,000 hours(T598,T599) at 85°C/85% RH rated voltage and maximum operational temperature life up to 125°C and 150°C respectively.
