The industry’s first AEC-Q200 polymer electrolytic capacitor

Delivering stability and endurance in extreme humidity and temperature environments, the T598 high humidity/high temperature series has been unveiled by KEMET. According to the manufacturer, this is the first polymer electrolytic capacitor that meets all of the requirements of the Automotive Electronics Council’s AEC-Q200 specification for passive components.

Building on the success of the T591 series, KEMET further refined the design, materials and manufacturing to ensure the T598 series delivers higher stability and endurance under harsh conditions. These improvements result in a design that exceeds the humidity bias testing requirements of +85°C with 85% relative humidity, in addition to delivering stable electrical performance at +125°C.

Typical applications include decoupling and filtering of DC/DC converters in automotive infotainment and ADAS, as well as industrial and telecomms applications where harsh conditions such as high humidity and temperature are of concern.

The T598 series is available in capacitances of up to 330μF and rated voltages up to 16V. The qualification test plan is in accordance with AEC-Q200 and these products are manufactured in an ISO TS 16949 certified facility. This series is available for Production Part Approval Process (PPAP), Part Submission Warrant (PSW) and Change Control Notification.

Dr. Philip Lessner, Senior Vice President and Chief Technology Officer, KEMET, commented: “In 1999, KO-CAP offered engineers a breakthrough in high capacitance, low ESR and long lifetime capacitors. Since this time, designers have utilised polymer electrolytic capacitors in space-constrained or high performance applications. Now that KO-CAPs meet all of the AEC-Q200 requirements, engineers can incorporate these innovative capacitors into automotive and other harsh environment applications.”
