GUS-QS8A-03-6342-GF Description

The GUS-QS8A-03-6342-GF from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a 16-pin QSOP package with gull-wing SMD termination, this device offers a 63.4KΩ resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for demanding circuits requiring isolation (denoted by "ISOL" circuit designator). The thin-film technology provides superior accuracy and reliability compared to thick-film alternatives.

GUS-QS8A-03-6342-GF Features

• Precision Thin Film: 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 ±0.1mm dimensional tolerances, ideal for space-constrained PCBs.
• High Power Handling: 0.1W per resistor (0.75W total) derated up to 125°C, outperforming standard networks in thermal management.
• Isolated Design (ISOL): Each resistor is electrically isolated, enabling flexible circuit configurations.
• Robust Construction: Gull-wing leads ensure secure surface mounting, while the tube packaging protects during transit.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and instrumentation use.
