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 Ohmcraft method of manufacturing offers the best characteristics of both methods, plus adds many unique features. Ohmcraft 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 method allows control of process parameters to very tight tolerances. The result is chip resistors with outstanding stability and performance.
Low Noise PerformanceOhmcraft resistors exhibit exceptional noise characteristics. The graph on the right demonstrates the comparison of a resistor written by Ohmcraft, and an equivalent resistor printed using a standard thick-film process. The longer serpentine path which uses lower resistivity inks, and the smoother edges created by “writing” rather than “screening” combine to make one of the lowest noise generating resistors in the market. |
