Overview
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.
