The T599 KO-CAP High Humidity/High Temperature Performance Polymer series delivers stability and endurance under harsh humidity and temperature conditions.

KEMET refined the design, materials and manufacturing of the T598 family to give the T599 more stability and endurance under harsh conditions. The T599 capacitors pass 1,000 hours of humidity bias testing under 85°C with 85% relative humidity at rated voltage, and endurance testing at 150°C up to 1,000 hours, making it the only 150°C AEC-Q200 qualified polymer electrolytic capacitor available today says the company.

“Since 2015, T598 capacitors have offered engineers a breakthrough in high capacitance, low ESR and long lifetime with full AEC-Q200 qualification,” said Dr. Philip Lessner, KEMET Senior Vice President and Chief Technology Officer. “Over the last two years, designers have used polymer electrolytic capacitors in space-constrained or high-performance applications. Now that KO-CAPs meet both 150°C and AEC-Q200 guidelines, automotive engineers can incorporate these innovative devices into powertrain designs.”

Qualification is compliant with AEC-Q200 guidelines and parts are manufactured in an ISO TS 16949 certified plant. T599 is also available for Production Part Approval Process (PPAP), Part Submission Warrant (PSW) and change control notification.
