Tough high-performance organic capacitor delivers automotive-grade reliability

The new Kemet organic capacitor (KO-CAP) is now available from TTI Europe. The sold electrolytic capacitor with a conductive polymer cathode combines the low ESR of multilayer ceramic, the high capacitance of aluminium electrolytic and the volumetric efficiency of tantalum into a single surface-mount package. Unlike liquid-electrolyte-based capacitors, KO-CAP delivers a long operational life and high ripple current capabilities. The T598 high-performance automotive-grade polymer electrolytic capacitor has been specifically developed to deliver greater stability and reliability in harsh environmental conditions. Due to special enhancements incorporated in its materials and design, the KEMET T598 delivers 1,000 hours under 85°C/85% RH/VR and fully complies with AEC-Q200 Qualification Testing. It is manufactured in an ISO TS16949 certified plant and is subjected to PPAP/PSW and change control. The device meets or exceeds EIA standard 535BAAC. Performance characteristics include an operating temperature range of -55C to +125C and a rated capacitance range of 47 - 330µF at 120Hz/25C. Rated voltage is 6.3V - 16V. Typical applications include decoupling and filtering across products aimed at a number of markets, but it is particularly suited to automotive applications such as infotainment and input/output in DC-DC converters exposed to high humidity and temperatures.
