MacDermid Alpha Micromax 1738R is a screen-printable resistor composition from the 17G-Series, specifically formulated for gold (Au) conductor terminations. Offering 9-11 kΩ/sq sheet resistivity with ultra-low noise of 6-8 dB and TCR within ±100 ppm/°C, optimized for 850°C air firing in precision high-ohm hybrid circuit applications.
As a member of the Micromax 17G-Series, Micromax 1738R is a high-ohm gold-compatible thick-film resistor paste engineered specifically for hybrid circuits utilizing gold conductor metallization. This ultra-high-ohm composition delivers a sheet resistivity of 9-11 kΩ/sq with exceptional low noise performance of 6-8 dB — making it ideal for precision analog and low-signal applications where electrical noise must be minimized. TCR values are consistently within ±100 ppm/°C across hot and cold testing conditions.
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. It supports a 60-minute air firing cycle with a 10-minute peak hold at 850°C. The 17G-Series is fully blendable — adjacent members blend smoothly with no blend breaks. The material is free from intentionally added phthalates, cadmium and nickel oxide, and is RoHS compliant. Standard packaging includes 100G and 1000G containers.
