Ohmite MOX97021004FVE High-voltage super mox resistors have been developed Datasheet

Super Mox Series
High Voltage
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 noninductive 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
Uncoated resistor element pictured for
demonstration purposes only. Finished
product is coated with silicone.
requirements of high voltage power supplies, electron microscopes, X-ray systems, high resolution
CRT displays and geophysical instruments.
