Automotive Grade Capacitors For Harsh Environmental Applications

The latest KO-CAP and the industry’s first AEC-Q200 qualified polymer electrolytic capacitor as claimed by KEMET, delivers stability and endurance under harsh conditions.  The T598 series capacitor is suited for applications that 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.

The KEMET Organic Capacitor (KO-CAP) is a polymer capacitor with a Ta anode and Ta2O5 dielectric. A conductive organic polymer replaces the traditionally used MnO2 as the cathode plate of the capacitor. This results in very low ESR and improved capacitance retention at high frequency. The KO-CAP also exhibits a benign failure mode which eliminates the ignition failures that can occur in standard MnO2 tantalum types.

Leveraging the success of the T591 Series, KEMET has refined the design, materials and manufacturing process to ensure that T598 Series delivers high stability and endurance under harsh conditions, as stated in the release. Adding further, the release mentions that these improvements result in a design that exceeds the humidity bias testing requirements of 85 degrees Celsius with 85 per cent relative humidity in addition to delivering stable electrical performance at 125 degrees Celsius.

According to the press release, “The T598 Series is available today in capacitances of upto 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.”
