High Reliability KEMET Organic Capacitor (KO-CAP)
T541 Polymer Commercial Off-the-Shelf (COTS) Multiple Anode
Overview
The KEMET Organic Capacitor (KO-CAP) is a tantalum capacitor
with a Ta anode and Ta
2
O
5
dielectric. A conductive organic
polymer replaces the more common MnO
2
as the cathode plate
of the capacitor. This results in very low ESR and improved
capacitance retention at high frequency. This advancement
combined with the use of a multiple anode design delivers the
lowest ESR values available in the industry. The KO-CAP may
also be operated at steady state voltages at 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.
The T541 Series KO-CAP offers the same advantages as the
T530 Series but is also designed for the Commercial Off-the-Shelf
(COTS) requirements of military and aerospace applications. This
surface mount product offers a tin lead (SnPb) leadframe finish,
surge current testing options and standard or low ESR levels.

Performance Characteristics
* KEMET’s Polymer COTS (T540/T541 Series) capacitors are rated for operation between -55°C and +125°C. Parametric electrical performance remains within
stated specification limits after 1,000 hours of continuous operation and/or storage at +125°C. Long-term duty cycles or storage at or above +125°C may result in
an increase in ESR performance outside of the stated specification limits.
