Are you a designer looking for Automotive Capacitor alternatives? The existing full AEC-Q200 qualified series T598 (125ºC) and T599 (150ºC) from KEMET can help to provide better capacitance stability, better capacitance retention, lower ESR, higher ripple handling, and long life. Check out KEMET´s latest releases in High Voltage Automotive Polymer Capacitors (T598 series). With rated voltages up to 75V applications like the 48V boardnet can benefit from Polymer advantages like High Volumetric efficiency, reduced Board Space & Piece Count, mechanical robustness as well as extended lifetime.

13. ISO Pulse 7637-2 and VW80000 (E05 Load Dump)
Complete Evaluations
T598D336M035ATE065

14. KEMET has performed the ISO7637-2 Road vehicles — Electrical disturbances from conduction and coupling — Part 2:
Electrical transient conduction along supply lines only pulse tests and concluded that the 35V rated voltage products fully
comply with pulse1, 2a,2b,3a,3b, 4 and 5b(suppressed at 13,5+40V) and show limitation at 5a pulse. The 5a pulse limitation
requires up front definition of the pulse shape and parameters for an alternator with centralized load dump suppression or
not is use. In most new alternators, the load dump amplitude is suppressed (clamped) by the addition of the limiting diodes.
In addition KEMET performed the Special Load Dump testing E05 according the VW80000, issue 06-2013 – Electric and
Electronics Components in Motor Vehicles up to 3,5t . The summary of the results is shown in Table
