Very Low noise
The usual technologies used for manufacturing resistors
depend upon composite materials that have limitations.
Traditional thick-film process methods limit performance
characteristics and thin-film methods are limited in
attainable ohmic values.
Ohmcraft’s
fine line patterning
offers the best characteristics of both methods, plus adds
many unique features.
Ohmcraft’s
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
Ohmcraft
resistors
unmatched design efficiency, versatility, linearity, stability
and low noise. The
Ohmcraft’s
fine line patterning
methods allow control of process parameters to very tight
tolerances. The result is chip resistors with outstanding
stability and high voltage ratings.
Leaded resistors, dividers and networks are manufactured
using the same fine line patterning technologies. For
additional information on those products, please refer to the
appropriate data sheets.
Maximum Continuous Voltage:
Ohmcraft’s
high voltage chip resistors offer voltage
ratings that are much higher than conventional screen
printed resistors of the same size and resistive value.
