GUS-QS8A-03-1203-DB Description

The GUS-QS8A-03-1203-DB 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 120K Ohm resistance value with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70 to 125°C. Encased in a compact 16-pin QSOP package with gull-wing terminations, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for high-density PCB designs. Its 100V maximum voltage rating and thin-film technology provide excellent reliability in precision circuits.

GUS-QS8A-03-1203-DB Features

• High Precision: 0.5% tolerance and ±25ppm/°C TCR for stable performance in critical applications.
• Robust Construction: Thin-film technology ensures low noise and high stability.
• Compact Design: QSOP-16 package (4.9mm x 6.02mm x 1.47mm) with 0.64mm pitch for space-constrained layouts.
• Isolated Configuration: 8 independent resistors (ISOL circuit designator) for flexible circuit design.
• Wide Operating Range: -55°C to +125°C with derated power up to 125°C.
• Surface-Mount Ready: Gull-wing terminations for reliable SMD assembly.
