GUS-QS0B-03-8661-GF Description

The GUS-QS0B-03-8661-GF from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 8.66KΩ resistance value per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Packaged in a compact 20-pin QSOP (Quarter-Small Outline Package) with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs. The thin-film technology provides superior accuracy and reliability compared to thick-film alternatives, while the tube packaging ensures safe handling and storage.

GUS-QS0B-03-8661-GF Features

• Precision Thin Film: Delivers ±25ppm/°C thermal stability and 2% tolerance for critical analog/digital circuits.
• High-Density Design: QSOP-20 package (8.66mm × 6.02mm × 1.47mm) with 0.64mm pitch optimizes board space.
• Robust Performance: Rated for 125°C max operating temperature and derated power up to 125°C.
• Versatile Termination: Gull-wing leads enable reliable surface-mount (SMD) assembly and reflow compatibility.
• Non-Automotive Grade: Ideal for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
• Non-RoHS: Suitable for legacy or exempted systems.
