Ultra Low ESR, High Capacitance retention and AEC-Q200 qualified

KEMET introduced its T598 High Humidity/High Temperature Series, 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 degrees Celsius with 85% relative humidity in addition to delivering stable electrical performance at 125 degrees Celsius.

"In 1999, KO-CAP offered engineers a breakthrough in high capacitance, low ESR and long lifetime capacitors, since this time, designers have utilized 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.

The T598 Series is available today in capacitances of up to 330 microfarads and rated voltages up to 16 volts. 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.

Typical applications include decoupling and filtering of DC-to-DC converters in automotive infotainment and advanced driver assistance, as well as industrial and telecom applications where harsh conditions such as high humidity and temperature are of concern.
