KEMET Organic Capacitor (KO-CAP
®
) – High Reliability
T540 COTS Polymer Electrolytic for High Reliability
Applications, 2.5 – 63 VDC
Overview
The KEMET Organic Capacitor (KO-CAP) is a solid
electrolytic capacitor with a conductive polymer cathode
capable of delivering very low ESR and improved
capacitance retention at high frequencies. KO-CAP
combines the low ESR of multilayer ceramic, the high
capacitance of aluminum electrolytic and the volumetric
efficiency of tantalum into a single surface mount package.
Unlike liquid electrolyte-based capacitors, KO-CAP
has a very long operational life and high ripple current
capabilities.
The T540 COTS Polymer Electrolytic offers the same
performance advantages as other KO-CAP series with
screening options associated with high reliability ("Hi-
Rel") applications. These Commerical-Off-The-Shelf
(COTS) grade components are built with a tin-lead
(SnPb) termination finish and offer several surge current
screening options. The recommended application derating
for these capacitors is 10 – 20%, rendering them suitable for
application voltages from 2.25 to 50 VDC.
The T540 Series is the first polymer electrolytic capacitor
available with failure rate options as defined by KEMET's
KO-CAP Reliability Assessment method. This method utilizes
accelerated conditions (voltage and temperature) applied to
board-mounted samples to assess long term device reliability.
The failure rates available are B (0.1% per 1,000 hours), C
(0.01% per 1,000 hours) and D (0.001% per 1,000 hours). The
KO-CAP Reliability Assessment method was developed as
a result of over ten years of research and is described in
numerous papers available on www.kemet.com.

Typical applications include decoupling and filtering in defense and aerospace applications that require low ESR or a benign
failure mode.
When extreme temperatures and humidity are taken into account, polymer capacitors offer a number of advantages over
other types of capacitors. KEMET continues to investigate the behavior of polymer capacitors in extreme conditions. If
you have questions about using these capacitors in a specific environment or application, we suggest you contact your
local KEMET representative or Field Application Engineer. You may also refer to “Considerations for Polymer Capacitors in
Extreme Environments” located at

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.
