KEMET Organic Capacitor (KO-CAP)
T530 High Capacitance/125°C Rated Polymer Tantalum
Overview
The KEMET Organic Capacitor (KO-CAP) is a tantalum
capacitor with a Ta anode and Ta2O5 dielectric. A conductive
organic polymer replaces the traditionally used MnO2 as the
cathode plate of the capacitor. This results in very low ESR and
improved capacitance retention at high frequency. The KO-
CAP also exhibits a benign failure mode which eliminates the
ignition failures that can occur in standard MnO2 tantalum types.
KO-CAPs may also be operated at steady state voltages up to
90%ꢀofꢀratedꢀvoltageꢀforꢀpartꢀtypesꢀwithꢀratedꢀvoltagesꢀofꢀ≤10ꢀ
volts and up to 80% of rated voltage for part types >10 volts with
equivalent or better reliability than traditional MnO2 tantalum
capacitors operated at 50% of rated voltage.
The T530 Series KO-CAP offers the same advantages as
the T520 Series but also has the added advantages of higher
capacitance, 125°C performance capability, higher ripple current
handling capability and a lower ESR range. Packaged as multiple
anodes to reduce the depth that the signal must penetrate, this
parallel arrangement reduces the ESR further still to achieve the
highest capacitance and lowest ESR of any other type of surface
mountꢀcapacitorꢀwithꢀtypicalꢀESRꢀvaluesꢀasꢀlowꢀasꢀ4ꢀmΩ.ꢀWithꢀ
reduced ESR, the enhanced capacitance retention at higher
frequencies provides the lowest total capacitance and most
economical solution for high power applications.
