Application Notes

Due to the high voltage which can appear between the end cap and any adjacent metal part, resistors should be

mounted at an adequate distance from other conductors.

For some ultra-high voltage applications it is required to immerse the components in oil or SF6 gas or pot them in void-

free silicone compound to reduce corona or surface tracking. The epoxy protection, code P, is suitable for these

applications.

The axial termination should not be bent closer than twice the diameter of the terminal wire from the resistor body.
