MacDermid Alpha Micromax 2021 is a high-ohm resistor paste from the 2000 Series B Group, offering 90-110 Ω/sq sheet resistivity — the highest in the B Group — with the highest voltage rating of 11 V/mm and cold TCR ≥-75 ppm/°C. Optimized for high-resistance networks and high-voltage hybrid circuits.
Part of the Micromax 2000 Series B Group, Micromax 2021 is a high-ohm resistor paste engineered for hybrid microcircuits requiring the highest resistance values and voltage handling capability in the B Group. This composition delivers the highest standard working voltage of 11 V/mm and short term overload voltage of 28 V/mm, making it ideal for precision voltage dividers and high-voltage applications. The paste achieves excellent cold TCR of ≥-75 ppm/°C with hot TCR of 0 to 50 ppm/°C, ensuring stable performance across temperature variations. The B Group designation means this paste is blendable with 2004, 2011, 2015, 2031, 2041, 2051 and 2061.
With a sheet resistivity of 90-110 Ω/sq, Micromax 2021 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.
