GUS-QS8B-00-4020-GF Description

The GUS-QS8B-00-4020-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 402Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating (0.05W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C, derated for optimal thermal management. The ±250ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for stable, low-drift applications. Its gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density layouts.

GUS-QS8B-00-4020-GF Features

• Precision Thin Film Technology: Delivers low noise and high stability 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).
• Robust Power Handling: 0.75W total dissipation (15 resistors) with derating up to 125°C.
• Automotive-Grade Alternatives: While not PPAP or automotive-qualified, its 125°C max operating temp suits industrial and telecom environments.
• Non-RoHS Compliance: Ideal for legacy systems requiring leaded components.
• BUS Circuit Designator: Optimized for bus termination, voltage division, and pull-up/down networks.
