KEMET Organic Capacitor (KO-CAP)
T545 Series High Energy Polymer Tantalum
Overview
The KEMET Organic Capacitor 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 polymer technology also exhibits
a benign failure mode which eliminates the ignition failures that
can occur in standard MnO2 tantalum types. Ta polymers may
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 MnO2 tantalum capacitors operated at 50% of rated
voltage.
The T545 Series was developed to deliver the highest energy per
CC of any tantalum surface mount device (SMD). This capability
makes this capacitor an excellent solution for designs requiring
high energy at relatively low voltages, such as data hardening or
data vaulting for solid state drives (SSD's). The T545 Series High
Energy Polymer Tantalum Surface Mount Capacitor captures the
best features of multilayer ceramic capacitors (low ESR and high
frequency capacitance retention), aluminum electrolytics (higher
capacitance and benign failure mode) and proven solid tantalum
technology (volumetric efficiency, surface mount capability and
extremely long life). In addition, this series is subjected to 100%
thermal shock and voltage aging to insure long term reliability.
