Polymer electrolytic with automotive ratings

July 16, 2015 // By Graham Prophet
Kemet’s automotive grade polymer electrolytic capacitors, the T591 series offering stability and endurance under harsh humidity and temperature conditions, now includes variants up to 50V for use on both 12V and 24V power rails.

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, according to the company. The T591 KO-CAP is available up to 330 µF with operating temperatures up to 125C, with low ESR and with improved capacitance retention at higher frequencies. 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.
