super Mox series High Voltage High-voltage Super Mox resistors have been devel- oped to meet the precision temperature stability requirements of high-accuracy and high-voltage Uncoated resistor element pictured for systems. Super Mox combines proprietary non- demonstration purposes only. Finished product is coated with silicone. inductive resistance system and design to achieve low temperature coefficient, low voltage coefficients, requirements of high voltage power supplies, elec- high stability and increased high operating voltages. tron microscopes, X-ray systems, high resolution These resistors are designed to meet the demanding CRT displays and geophysical instruments. series sPeciFicatiONs Power Max.
