Comparative evaluation and analysis of the 2008 Toyota Lexus, Camry and 2004 Prius DC link capacitor assembly vs. the SBE Power Ring DC link capacitor

Abstract

US Department of Energy, Oak Ridge National Laboratories (ORNL) and SBE, Inc. report test results comparing the Toyota Lexus, Camry, Prius (both new and end of life) and Kemet capacitors with the SBE PowerRing. While exact comparisons are difficult because of size, shape and terminal configurations the SBE capacitors showed from 4 to 8 times lower temperature rise than the others tested and with substantial volumetric reduction as well.
