MacDermid Alpha Micromax 2051 is the highest resistance (90-110 kΩ/sq) and highest voltage (148 V/mm) composition in the entire 2000 Series. With dual A+B group blendability, this paste sets the benchmark for extreme high-resistance, ultra-high-voltage hybrid circuit applications.
As the record-holder of the Micromax 2000 Series, Micromax 2051 is the highest resistance and highest voltage resistor paste in the entire series. This composition delivers an exceptional standard working voltage of 148 V/mm and short term overload voltage of 370 V/mm — surpassing all other 2000 Series members by a significant margin. With a sheet resistivity of 90-110 kΩ/sq, it offers the highest resistance range available in the series. The paste achieves hot TCR of 0 to 50 ppm/°C and cold TCR of ≥-75 ppm/°C, ensuring stable performance across temperature variations.
With a sheet resistivity of 90-110 kΩ/sq, Micromax 2051 supports the most demanding 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.
