GUS-QS8B-01-5490-GG Description

The GUS-QS8B-01-5490-GG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package contains 15 resistors, each with a 549 Ω resistance value and a tight 2% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a ±100ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range of 70°C to 125°C. The gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density mounting.

GUS-QS8B-01-5490-GG Features

• Precision Thin Film Technology: Offers low noise and high stability for sensitive circuits.
• Compact QSOP Package: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• High Power Handling: 0.75W total dissipation (15 resistors) at 125°C max operating temperature.
• Automated Assembly Ready: Gull-wing leads and surface-mount design optimize pick-and-place efficiency.
• Broad Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation use.
• Non-Automotive (PPAP No): Ideal for non-automotive precision applications where RoHS compliance is not mandatory.
