KEMET Organic Capacitor (KO-CAP
®
) – High Reliability
T543 COTS Polymer Electrolytic, 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 T543 COTS Polymer Electrolytic capacitor is an upscreened
version of the industrial T520 KO-CAP. The T543's upscreeed
option includes surge current testing of 10 cycles at +25°C and 10
cycles at −55°C/+85°C. In addition to 100% Tin (Sn) terminations
a Tin-lead (SnPb) option is also available. The recommended
application derating for these capacitors is 10 – 20%, rendering
them suitable for application voltages from 2.25 to 50 VDC.

Applications
Typical applications include DC/DC converters, switch mode and point of load power supply, radar pulse capacitor and
telecommunications (mobile phone and base station). Other general applications include decoupling and filtering in applications
requiring low ESR or a benign failure mode.
When extreme temperatures and humidity are taken into account, polymer tantalum capacitors offer a number of advantages over
other types of capacitors. KEMET continues to investigate the behavior of polymer tantalum 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
www.kemet.com/ExtremePolymerPaper.
Environmental Compliance
RoHS Compliant (6/6) according to Directive 2002/95/EC when ordered with 100% Sn solder.
