Vacuum and space application
The heavy duty construction
of the Power-Mox series make
them durable in most high
voltage industrial applications.
This product is well known for
its high voltage ratings, low
voltage coefficients, very high
ohmic values, and resistor
divider options. Terminations
can be selected to adapt to
most mounting schemes.
