The 100% screening factory test is carried out at 2,700 VDC. The
voltage level is selected to meet the requirements in applicable
equipment standards. All electrical characteristics are checked
after the test. It is not permitted to repeat this test as there is a
risk to damage the capacitor. KEMET is not liable in such case for
any failures.
