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
