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 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. Combining this
advancement 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 defense and aerospace applications. This
surface mount product offers a tin lead (SnPb) leadframe finish,
surge current testing options and standard or low ESR levels.
Benefits
• ESR: 10 mΩ to 40 mΩ
• 125°C maximum operating temperature
• Polymer cathode technology
• High frequency capacitance retention
• Benign failure mode
• Capacitance: 22 µF to 1,500 µF
• 100% accelerated steady state aging
• Surge current testing options
• Utilizes multiple tantalum anode technology
• Volumetric efficiency
• Use at up to 90% of rated voltage (10% derating)
for part types ≤ 10 V
• Use at up to 80% of rated voltage (20% derating)
for part types > 10 V
• Very low ESR
• EIA standard case sizes

* 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.
