Micromax 0050A delivers extreme high resistivity (285-115 kΩ/sq) with exceptional ESD stability (DeltaR -0.2 to 0.2%) and low noise performance (≤ -6 dB) — engineered for ultra-high resistance chip resistor production with 850°C fast firing.
Micromax 0050A is an ultra-high resistance thick film paste specifically developed for chip resistor applications requiring extreme resistance coverage and precision electrical performance. This grade delivers exceptional ESD stability with DeltaR of -0.2 to 0.2% using a 100pF/1500Ω network — offering superior protection for sensitive high resistance designs. It also provides excellent power handling stability for demanding operating conditions and low Quan-Tech noise (≤ -6 dB) for signal integrity. The material offers well controlled TCRs with minimal length and thickness effects across the entire ultra-high resistance range.
This resistor paste provides linear blend behavior between adjacent members, enabling broad high resistance coverage from 285-115 kΩ/sq without sacrificing electrical properties. It is optimized for high-resolution screen printing at speeds up to 30 cm/sec and supports co-firing with high silver terminations at 850°C peak temperature. The cadmium-free, nickel-free and phthalate-free formulation meets international environmental standards including RoHS and REACH. Standard packaging options are 100G and 1000G.
