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 temperature coefficient, low voltage coefficients, high stability and
increased high operating voltages. These resistors are designed
to meet the demanding requirements of high voltage power supplies, electron microscopes, X-ray systems, high resolution CRT
displays and geophysical instruments.
