KEMET Organic Capacitor (KO-CAP
®
) – High Reliability
T543 Up-Screen Commercial
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 upscreened 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.
Benefits
• Extremely low ESR
• High frequency capacitance retention
• 100% accelerated steady state aging
• 100% surge current tested
• Tape & Reel standard packaging per EIA 481
• Volumetrically efficienct
• Surge options at 25°C and −55°C/+85°C
• EIA standard case sizes
• Halogen-free epoxy and RoHS compliant
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, when used in extreme environments. 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 representative or field application engineer to
discuss the specific details of your application (see “Considerations for Polymer Capacitors in Extreme Environments”
located at www.kemet.com/ExtremePolymerPaper).

Why is there no response when checking the registers with axd?
Everyone, when I use axd to debug the program, I can't view the registers using memory. For example, when I view the GPGDAT register and enter 0x56000064, the memory address will become 0x0 again. Wha...
