GUS-QS8A-03-1740-FF Description

The GUS-QS8A-03-1740-FF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 8-resistor isolated network features a 174Ω resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin QSOP (QSOP-16) package, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) with gull-wing terminations for reliable SMT soldering. The 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for moderate-power applications, while its 100V maximum voltage rating ensures robustness in demanding circuits.

GUS-QS8A-03-1740-FF Features

• Precision Thin-Film Technology: Delivers high accuracy (±1%) and low TCR (±25ppm/°C) for stable performance in temperature-varying environments.
• Isolated Network (ISOL): Each resistor is electrically isolated, providing flexibility in circuit design for signal conditioning, pull-up/down networks, or voltage division.
• Compact QSOP Package: Space-saving 16-pin QSOP with 0.64mm terminal pitch ideal for high-density PCBs.
• Robust Construction: Gull-wing terminations ensure reliable solder joints, while the rectangular package shape simplifies automated placement.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power handling up to 125°C.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and consumer electronics where PPAP compliance is not required.
