GUS-QS8B-01-1021-GF Description

The GUS-QS8B-01-1021-GF 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 integrates 15 resistors, each with a 1.02KΩ resistance value, a tight 2% tolerance, and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a maximum voltage rating of 100V, this network is engineered for reliability in demanding circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density mounting.

GUS-QS8B-01-1021-GF Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and stability 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/length, ±0.2mm depth).
• High Power Density: 0.75W total dissipation in a miniature footprint, ideal for space-constrained designs.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated power up to 125°C).
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its robust construction suits industrial and telecom applications.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded soldering.
