Test Voltage Between Terminals
The 100% screening factory test is carried out at 1,800 VDC. The
voltage level is selected to meet the requirements in applicable
equipment standards. All electrical characteristics are checked
after the test.
In DC Applications Recommendedvoltage≤630VDC
Power Ratings
The average losses may reach 0.5 W provided the surface
temperaturedoesnotexceed+85°C.Formaximumpermitted
