KEMET recently extended its automotive-grade polymer electrolytic capacitors. The T591 High Performance Automotive Grade Polymer Electrolytic Series delivers stability and endurance under harsh humidity and temperature conditions. The new extensions include options up to 50V for both 12V and 24V power rails.
"These new KO-CAPs are ideal for demanding applications where a combination of high temperature and humidity is a concern, such as in transportation, telecommunications, industrial and avionics,"Â says Cristina Mota Caetano, Technical Product Marketing Director at Kemet. She adds, "Polymer material, design and manufacturing process enhancements allow the T591 to deliver high reliability when tested to 500 hours in 85 degrees Celsius, with 85% relative humidity and while voltage is applied."
The T591 KO-CAP is available in capacitances up to 330 microfarads and features operating temperatures up to 125° C. These extensions to KEMET's KO-CAP high performance series deliver very low ESR and improved capacitance retention at higher frequencies allowing for miniaturization and piece count reduction. The qualification plan was based on AEC-Q200 guidelines and the products are manufactured in an ISO TS 16949 certified plant. The series is available with Production Part Approval Process (PPAP), Part Submission Warrant (PSW) and change control notification.
