INTENDED OPERATING CONDITIONS
Electrical ratings are determined by various factors, including dielectric strength, geometry and system operating pressure. Please note that all ISI catalog products are electrically rated for operation with one side in dry atmospheric conditions and the other side in a vacuum environment with a maximum system
pressure of 1 x 10-4 Torr. We advise that users make allowances for deviations from stated operating parameters and take adequate safety precautions when feedthroughs are operated at high voltages or high currents.
