Custom Leaded Resistor Networks (CN Series)

 Printable PDF version of datasheet


Ohmcraft’s revolutionary fine line, thick film technology, called FineFilm, provides an entirely new level of performance and stability in custom leaded resistor networks.

  • Resistance Values to 2 Gigohms
  • Ultra High Stability
  • TCR to 10 ppm/°C
  • Voltage ratings to 100,000 Volts
  • Very Low Noise
  • VCR to 0.05 ppm/V
  • TCR Tracking to 5 ppm/°C
  • Tolerances to 0.1%

The usual hybrid technologies for manufacturing resistors depend upon composite materials that have limitations. Traditional thick-film methods severely limit performance characteristics and thin-film methods are limited in attainable ohmic values. The FineFilm method of manufacturing offers the best characteristics of both methods, plus adds many unique features. FineFilm resistors feature a longer, high-aspect ratio trace of lower resistivity film. The combination of long line, high-aspect ratio, and higher conductivity film, give FineFilm resistors unmatched design efficiency, versatility, linearity, stability and low noise. The FineFilm method allows control of process parameters to very tight tolerances. The result is networks with outstanding tracking performance over a wide range of temperature, voltage and ohmic values.

Our unique CAD/CAM direct write system allows us to quickly custom fabricate resistor network:

  • Immediate prototyping
  • No special tooling
  • Easy design changes
  • Short or long runs
  • High quality

Design Flexibility

The long serpentine pattern used in manufacturing FineFilm Custom Networks (CNs), coupled with the use of low ohms/ square thick film inks, makes it possible to create virtually any divider ratio. For example, Ohmcraft produces 7 decade networks (20K to 20G ohm) with precision ratio tolerances. What are your needs? Low noise, low TCR, low VCR, and many other features add up to the finest leaded networks in the market today. 

We would be glad to work with you on your custom network needs:

Because each network is different, there is no standard part number. Each network is assigned it’s own number as it is received by the factory. To obtain a quote on a network, please contact us and include the following information:
