The KEMET low-ESR polymer series 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 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 T527 series KO-CAP combines improved packaging efficiency with a low-profile design through the use of facedown terminal technology. This series offers high capacitance in a 3216-10 (3.2 mm (L) x 1.6 mm (W) x 1.0 mm (H)) package size. The T527 series is ideal for use in densely populated circuits such as smart-phones and digital cameras where space restrictions do not allow for larger and more commonly available case sizes.
