Power-Mox
Precision Power Thick Film
High Voltage/High Resistance Tubular
Non inductive
version shown
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.

required. EXAMPLE:
RT = 500MΩ 5%
R1 = 499.5MΩ 5%
R2 = 500KΩ 1%
Ratio = RT / R2 = 1,000: 1, 1%
