KEMET Organic Capacitor (KO-CAP) T543 Series Polymer Tantalum COTS Overview The KEMET Organic Capacitor is a tantalum capacitor with a Ta anode and Ta2O5 dielectric. A conductive organic polymer replaces the traditionally used MnO2 as the cathode plate of the capacitor. This results in very low ESR, improved capacitance retention at high frequency and improved ripple current handling capability. The polymer technology also exhibits a benign failure mode which eliminates the ignition failures. T.

KEMET Organic Capacitor (KO-CAP) T543 Series Polymer Tantalum COTS Overview The KEMET Organic Capacitor is a tantalum capacitor with a Ta anode and Ta2O5 dielectric. A conductive organic polymer replaces the traditionally used MnO2 as the cathode plate of the capacitor. This results in very low ESR, improved capacitance retention at high frequency and improved ripple current handling capability. The polymer technology also exhibits a benign failure mode which eliminates the ignition failures. Tantalum polymers may also be operated at voltages up to 90% of rated voltage for part types with rated voltages of ≤ 10 volts and up to 80% of rated voltage for part types > 10 volts with equivalent or better reliability than traditional MnO2 tantalum capacitors operated at 50% of rated voltage. The T543 Series Polymer Tantalum COTS is an upscreened version of KEMET's commercial polymer product offering and captures the best features of multilayer ceramic capacitors (low ESR, high frequency capacitance retention), aluminum electrolytic capacitors (higher capacitance, benign failure mode), and proven solid tantalum technology (volumetric efficiency, surface mount capability, extremely long life). The T543 also offers an option for surge current testing (10 cycles at +25ºC and 10 cycles at -55ºC/+85ºC) and termination finish (SnPb and 100% Sn). Benefits • • • • • • • • • • • • • • Extremely low ESR -55°C to 105°C operating temperature range Polymer cathode technology High frequency capacitance retention Non-ignition failure mode Capacitance up to 1,500 µF Enhanced derating 100% accelerated steady state aging 100% surge current tested Taped and reeled per EIA 481–1 Volumetric efficiency and self-healing mechanism Termination options (SnPb and 100% Sn) Surge options at 25ºC and -55ºC/85ºC EIA standard case sizes 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. Environmental Compliance RoHS Compliant (6/6) according to Directive 2002/95/EC when ordered with 100% Sn solder. One world. One KEMET © KEMET Electronics Corporation • P.O.
