This slide shows two calculator result comparisons. It compares the performance of a 550C inverter grade 105°C capacitor to a same-size DCMC low-cost screw terminal capacitor. The 550C has only 3700µF at 450V, while the DCMC has 5600µF at 450V. Both capacitors are running at 450V with 20A of 360Hz ripple and 25 amps of 2kHz ripple, thus simulating a harsh switching application with ripple current from rectification and from powering a DC-to-DC converter or inverter load. The results show that the 550C would last about 20 years and the DCMC about one year.
