150°C automotive polymer electrolytic capacitors



Called the T599 series, the parts are based on the existing T598 series. “Kemet refined the design, materials and manufacturing to ensure T599 delivers higher stability and endurance under harsh conditions,” said the firm.

The parts 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, “rendering it the only 150°C AEC-Q200 qualified polymer electrolytic capacitor available today”, claimed the firm.

“Since 2015, T598 capacitors have offered engineers high capacitance, low ESR and long lifetime with full AEC-Q200 qualification,” said Kemet CTO Dr Philip Lessner. “Over the last two years, designers have utilised 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 power train 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.
