AEC-Q200 Qualified Polymer Electrolytic Capacitor Tackles Extreme Humidity and Temperatures

07 August 2015

The KEMET T598 High Humidity/High Temperature Series is the first polymer electrolytic capacitor to meet all requirements of the Automotive Electronics Council’s AEC-Q200 specification for passive components.

The T598 KO-CAP meets AEC-Q200 requirements for automotive and other harsh environment applications.The T598 KO-CAP meets AEC-Q200 requirements for automotive and other harsh environment applications.KEMET refined the design of the T591 Series, as well as materials and manufacturing, to ensure the T598 Series delivers higher stability and endurance under harsh conditions. As a result, the design exceeds the humidity bias testing requirements of 85 ° Celsius with 85% relative humidity in addition to delivering stable electrical performance at 125 ° Celsius.

The T598 Series is available 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.

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.

“In 1999, KO-CAP offered engineers a breakthrough in high capacitance, low ESR and long lifetime capacitors,” says Dr. Philip Lessner, KEMET senior vice president and chief technology officer. “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.”
