KEMET Organic Capacitor (KO-CAP)
T525 125°C Rated Polymer Tantalum
Overview
The KEMET Organic Capacitor (KO-CAP) is a tantalum capaci-
tor with a Ta anode and Ta 2 O 5 dielectric. A conductive organic
polymer replaces the traditionally used MnO 2 as the cathode
plate of the capacitor. This results in very low ESR and improved
capacitance retention at high frequency. The KO-CAP also exhib-
its a benign failure mode which eliminates the ignition failures
that can occur in standard MnO 2 tantalum types. KO-CAPs may
also be operated at steady state voltages up to 90% of rated
voltage for part types with rated voltages of ≤ 10 volts and up to 
Benefits
80% of rated voltage for part types > 10 volts with equivalent or
better reliability than traditional MnO 2 tantalum capacitors operated
at 50% of rated voltage. The T525 Series KO-CAP Low ESR Poly-
mer is KEMET’s 125°C rated tantalum polymer capacitor. This part
offers the same advantages as the T520 Series such as low ESR,
high frequency capacitance retention and a benign failure mode.
The T525 Series is often the series of choice when considering
automotive or industrial type applications.
