Super Mox Series Datasheet

High Voltage 

Res SuperMox  product image

 

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 requirements of high voltage power supplies, electron microscopes, Xray systems, high resolution CRT displays and geophysical instruments.
