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. The technology combines the low ESR of the 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 a high ripple current capabilities.

The T597/T598/T599 Automotive Grade Polymer capacitors deliver higher capacitance and ESR stability under harsh environmental conditions. Enhancements to the design and selected material upgrades were introduced to deliver 1,000 hours (T597, T598, T599) at 85°C/85% RH rated voltage and to fully comply with the AEC-Q200 qualification testing with maximum operational temperature up to 125ºC and 150ºC respectively. In addition, the T598 Series is now available with Sn/Pb Termination finish and a surge current option per MIL-PRF-55365.

These capacitors are manufactured in an ISO TS 16949 certified plants and are subjected to PPAP/PSW, as well as change control.
