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 high voltage applications it is required to immerse the

components in oil or gas to reduce the effects or corona and surface

tracking. A special lacquer is available, suitable for immersion in

transformer oil or SF₆. When resistors are required to be plotted,

the preferred encapsulant is a silicone compound.

Resistors may be screwed together as a stick to provide an

assembly which will be capable of withstanding any desired

voltage, providing no individual resistor is subjected to a

greater stress or power dissipation than is recommended

in this data sheet.

For voltage dividers with a low resistance section below the medium

available value of an F43 resistor, it is entirely suitable to use an

RC Series resistor, available down to 1 ohm.

MATCHED SETS:

Matched sets can be supplied for use as voltage dividers. These may be screwed together to form sticks and, by selecting the KU

type of termination, a wire connection can be provided at each end of the stick.

Inquiries are welcome for special resistors and sets when resistor length, operating voltage or resistance values is outside

the catalog range.
