High-voltage Super Mox resistors have been developed to meet
the precision temperature stability requirements of high-accuracy
and high-voltage systems. Super Mox combines proprietary
non-inductive resistance system and design to achieve low tem
-
perature coefficient, low voltage coefficients, high stability and
increased high operating voltages. These resistors are designed
to meet the demanding requirements of high voltage power sup
-
plies, electron microscopes, X-ray systems, high resolution CRT
displays and geophysical instruments.
