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).
