KEMET Organic Capacitor (KO-CAP)
T543 Series Polymer Tantalum COTS
Overview
The KEMET Organic Capacitor is a tantalum capacitor 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, improved capacitance
retention at high frequency and improved ripple current handling
capability. The polymer technology also exhibits a benign failure
mode which eliminates the ignition failures. Tantalum polymers
may also be operated at voltages up to 90% of rated voltage
for part types with rated voltages of ≤ 10 volts and up to 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 T543 Series Polymer Tantalum COTS is an upscreened
version of KEMET's commercial polymer product offering and
captures the best features of multilayer ceramic capacitors (low
ESR, high frequency capacitance retention), aluminum electrolytic
capacitors (higher capacitance, benign failure mode), and proven
solid tantalum technology (volumetric efficiency, surface mount
capability, extremely long life). The T543 also offers an option
for surge current testing (10 cycles at +25ºC and 10 cycles at
-55ºC/+85ºC) and termination finish (SnPb and 100% Sn).
