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 The T543 COTS Polymer Electrolytic capacitor is an electrolytic capacitor with a conductive polymer cathode upscreened version of the industrial T520 KO-CAP. The T543 s capable of delivering very low ESR and improved upscreeed option includes surge current testing of 10 cycles capacitance retention at high frequencies. KO-CAP at +25C and 10 cycles at 55C/+85C. In addition to 100% combines the low ESR of multilayer ceramic, the high Tin (Sn) terminations a tin-lead (SnPb) option is also available. capacitance of aluminum electrolytic, and the volumetric The recommended application derating for these capacitors efficiency of tantalum into a single surface mount package. is 10 20%, rendering them suitable for application voltages Unlike liquid electrolyte-based capacitors, KO-CAP from 2.25 to 50 VDC. has a very long operational life and high ripple current capabilities. Benefits Extremely low ESR High frequency capacitance retention 100% accelerated steady state aging 100% surge current tested Taped and reeled per EIA 481 Volumetrically efficienct Surge options at 25C and 55C/+85C EIA standard case sizes Halogen-free Epoxy/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).
