Custom Leaded Resistor Networks
Ohmcrafts revolutionary fine film, thick film technology, called FineFilm, provides an
entirely new level of performance and stability in custom leaded resistor networks.
Design Flexibility
The long serpentine pattern used in manufacturing FineFilm
High Voltage Dividers (HVDs), coupled with the use of low
ohms/square thick film inks, makes it possible to create
virtually any divider ratio. For example, Ohmcraft has
produced 800 meg-ohm dividers with a 20,000:1 ratio. What
are your needs?
Low noise, low TCR, low VCR, and many other features add
up to the finest leaded divider in the market today.

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, highaspect
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 dividers with outstanding tracking performance
over a wide range of temperature, voltage and ohmic values.
Using the same method, a complete line of FineFilm
surface mount and wire bondable chip resistors are
manufactured. For information on those products, please
refer to the appropriate data sheets.
