GUS-QS0B-03-3000-GD Description

The GUS-QS0B-03-3000-GD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 19-resistor array features a 300Ω resistance value per resistor with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). Packaged in a 20-pin QSOP (QSOP-20) case with gull-wing terminations, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch, making it ideal for space-constrained designs. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this non-automotive, non-PPAP compliant component is optimized for industrial and commercial electronics.
