GUS-QS8B-02-1691-JF Description

The GUS-QS8B-02-1691-JF 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 1.69KΩ resistance value and a tight ±5% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it operates reliably across a wide temperature range of 70°C to 125°C, derated for optimal thermal management. The ±50ppm/°C temperature coefficient enhances stability in environments with fluctuating temperatures, while the 100V maximum voltage rating ensures robustness in high-voltage applications.

GUS-QS8B-02-1691-JF Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• Compact QSOP Package: Measures just 4.9mm (L) x 6.02mm (D) x 1.47mm (H), ideal for space-constrained designs.
• Gull Wing Termination: Facilitates reliable surface-mount (SMD) soldering with a 0.64mm terminal pitch for high-density layouts.
• High Power Density: 0.75W total dissipation in a miniature footprint, outperforming similar networks in thermal efficiency.
• Automotive-Grade Alternatives: While not automotive-qualified (PPAP: No), its 125°C max operating temp suits industrial and telecom applications.
• Non-RoHS Compliance: Suitable for legacy systems requiring leaded components.
