MacDermid Alpha Micromax 1759 is a screen-printable resistor composition specifically suited for sensor signal conditioning and instrumentation applications. Offering 10Ω/sq to 1MΩ/sq sheet resistivity with TCR below 100 ppm/°C and post-trim stability under 0.5% ΔR, engineered for precise sensor interface circuits.
Part of the Micromax Series 1700 materials system, Micromax 1759 is a precision resistor paste formulated for sensor signal conditioning and instrumentation applications. This composition delivers TCR values below 100 ppm/°C even with blended resistor formulations, ensuring accurate signal translation across temperature variations — critical for sensor bridge networks and precision analog interfaces. The material maintains stable performance despite variations in firing temperature, peak hold time, and resistor geometry.
With a sheet resistivity range spanning 10Ω/sq to 1MΩ/sq, Micromax 1759 supports diverse sensor interface requirements from low-resistance bridge configurations to high-impedance signal conditioning networks. The paste is optimized for 200-mesh stainless steel screens with 12-18 μm emulsion thickness, producing a dried film thickness of 22-28 μm. The 60-minute air firing cycle with a 10-minute peak hold at 850°C is compatible with Micromax 7484R Ag/Pd conductor terminations on 96% alumina substrates. Available in 100G and 1000G containers.
