Test Voltage Between Terminals

The 100% screening factory test is carried out at 3,200 VDC. The voltage level is selected to

meet the requirements in applicable equipment standards. All electrical characteristics are

checked after the test.

This test may not be repeated due to potential capacitor damage. KEMET is not liable for any

failures that result from repeating the test.
