GUS-QS8A-03-1052-BB Description

The GUS-QS8A-03-1052-BB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 10.5KΩ resistance value with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring exceptional stability across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing terminations, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits.

GUS-QS8A-03-1052-BB Features

• High Precision: 0.1% tolerance and ±25ppm/°C TCR for stable performance in critical applications.
• Robust Construction: Thin-film technology ensures low noise and high reliability.
• Compact Design: 4.9mm (L) x 6.02mm (D) x 1.47mm (H) QSOP package with 0.64mm terminal pitch for space-constrained PCBs.
• Isolated Configuration: Independent resistors (ISOL circuit designator) for flexible circuit design.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• Surface-Mount Ready: Gull-wing terminations for easy automated assembly.

GUS-QS8A-03-1052-BB Applications

This resistor network is ideal for:

• Precision voltage dividers in instrumentation and test equipment.
