General Purpose Polymer Capacitors2022-02-23T01:02:27+00:00

KEMET’s SMD polymer solutions for general usage market segments such as, consumer, computing, telecommunications and industrial, include the KO-CAP®, Neo-CAP, and AO-CAP series. These solid electrolytic capacitors feature a conductive polymer cathode, capable of delivering very low ESR with an improved capacitance retention at high frequencies and benign failure mode.

The technology combines the low ESR capability of an MLCC, the high capacitance of aluminum electrolytic, and the volumetric efficiency of tantalum MnO2 capacitors into a single surface mount package. Unlike liquid electrolyte-based capacitors, KO-CAP® has long operational life, and high ripple current capability.

KEMET has a transparent and ethical supply chain with regular audits by the Dodd-Frank Act legislation on conflict materials. Our polymer capacitors are environmentally friendly, lead-free, halogen-free molding compound, and RoHS compliant.
