HVL 43

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 high voltage applications it is required to immerse the components in oil or gas to reduce the effects of corona and surface tracking. The protective coating is suitable for these applications.

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

When the resistors are required to be plotted, the preferred encapsulant is a silicone compound.

For voltage dividers with a low resistance section below the minimum available value of 1k ohms, it is normal practice to use a Welwyn resistor, RC Series, obtainable down to 1ohm.
