GUS-QS8B-01-6491-G Description

The GUS-QS8B-01-6491-G from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter-Small Outline Package) device integrates 15 resistors, each with a 6.49KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The network operates within a wide temperature range of 70°C to 125°C (derated) and can withstand up to 125°C at full load, making it suitable for environments with thermal stress. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a ±100ppm/°C temperature coefficient, it delivers stable resistance characteristics under varying conditions. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating ensures reliability in high-voltage applications.

GUS-QS8B-01-6491-G Features

• Precision Thin Film Technology: Offers superior stability, low noise, and high accuracy compared to thick-film alternatives.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height, ±0.2mm depth), ideal for space-constrained designs.
• High Power Density: 0.75W total dissipation across 15 resistors, enabling efficient heat management in dense layouts.
• Automotive-Grade Alternatives: While not PPAP or Automotive certified, its 125°C operating range and robust construction make it suitable for industrial and telecom applications.
• Non-RoHS Compliant: May be preferred for legacy systems requiring specific material properties.
