KEMET T520 Series (KO-CAP) polymer tantalum capacitors offer the best features of multilayer ceramic (low ESR, high frequency capacitance retention), aluminium electrolytic (higher capacitance, benign failure mode), and proven solid tantalum technology (volumetric efficiency, surface mount capability, extremely long life). The KEMET T520 Organic Capacitor (KO-CAP) is a tantalum capacitor with a Ta anode and Ta2 O5 dielectric. A conductive organic polymer replaces the traditionally used cathode plate of the capacitor. This results in very low ESR and improved capacitance retention at high frequency.
Extremely low ESR Polymer cathode technology High frequency capacitance retention Non-ignition failure mode Volumetric efficiency Self-healing mechanism Halogen Free Epoxy
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 T52x/T530 provides the widest range of voltages, capacitance and case size options in the KO-CAP family and is suitable for general purpose DC applications for up to 48 volt DC voltage rails.
ESR values down to 5 mOhms Stable capacitance across temperature and voltage No aging effects High ripple handling Volumetrically efficient High frequency capacitance retention 100% accelerated steady state aging 100% surge current tested Halogen-free epoxy
