MacDermid Alpha Micromax 2019 is a high-ohm resistor paste from the 2000 Series A Group, offering 90-110 Ω/sq sheet resistivity — the highest in the A Group — with the highest voltage rating of 10 V/mm and cold TCR ≥-75 ppm/°C. Optimized for high-resistance networks, precision voltage dividers, and high-voltage hybrid circuits.
Part of the Micromax 2000 Series A Group, Micromax 2019 is a high-ohm resistor paste engineered for hybrid microcircuits requiring the highest resistance values and voltage handling capability in the A Group. This composition delivers the highest standard working voltage of 10 V/mm and short term overload voltage of 25 V/mm, making it ideal for precision voltage dividers and high-impedance applications. The paste achieves the best cold TCR in the A Group at ≥-75 ppm/°C with hot TCR of 0 to 50 ppm/°C, ensuring stable performance across temperature variations. The A Group designation means this paste is blendable with 2004R, 2009, 2031, 2041, 2051, 2061 and 2071.
With a sheet resistivity of 90-110 Ω/sq, Micromax 2019 supports high-resistance applications in hybrid circuits. The paste is optimized for 325-mesh screens with 10-15 μm emulsion thickness and print speeds of 10-20 cm/s. Drying is performed at 150-170°C. The material is fully compatible with Micromax 7484 Ag/Pd conductor compositions as well as Ag/Pt terminations. Available in 100G and 1000G containers.
