High Voltage Resistors Series 400 MX
Precision, Non-Inductive, Low TC
High Voltage Resistors Series 400 MX have been specifically developed
for use in high performance industrial and laboratory high voltage
systems. These precision high voltage resistors combine proprietary non-
inductive resistance system and design to achieve low temperature
coefficient, low voltage coefficients, high stability and increased high
operating voltages.
Low TC Precision High Voltage Resistors Series 400 MX are intended for
use in low outgasing applications, SF6 and oil. Typical applications are
medical systems like X-ray as well as power supplies or instruments.
