GUS-QS8B-01-3091-G Description

The GUS-QS8B-01-3091-G from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device integrates 15 resistors, each with a 3.09KΩ resistance and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a ±100ppm/°C temperature coefficient, it maintains stability across a wide operating range of 70°C to 125°C, making it suitable for environments with fluctuating thermal conditions. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust electrical performance, while the gull-wing termination ensures reliable solderability for automated assembly processes.

GUS-QS8B-01-3091-G Features

• Precision Thin Film Technology: Delivers low noise and high accuracy for sensitive analog/digital circuits.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth), ideal for space-constrained PCB designs.
• High Power Density: 0.75W total dissipation in a miniature footprint outperforms similar networks in power-handling capability.
• Wide Temperature Range: Operates reliably up to 125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• BUS Circuit Designator: Optimized for bus termination, voltage division, and pull-up/down networks in digital systems.
• Non-RoHS Compliant: May be preferred for legacy or high-reliability systems requiring traditional materials.
