GUS-QS8A-03-1740-FD Description

The GUS-QS8A-03-1740-FD 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 174Ω resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Packaged in a 16-pin QSOP with gull-wing terminations, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch, making it ideal for space-constrained PCB designs. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it balances power handling with precision.

GUS-QS8A-03-1740-FD Features

• High Precision: Thin-film technology delivers ±25ppm/°C TCR and 1% tolerance for critical analog/digital circuits.
• Robust Power Handling: 0.1W per resistor (0.75W total) at 125°C maximum operating temperature, derated for reliability.
• Compact & Durable: QSOP package with gull-wing leads ensures mechanical stability and ease of automated assembly.
• Isolated Design: Circuit designator "ISOL" indicates independent resistors, reducing crosstalk in signal conditioning.
• Wide Compatibility: Suitable for industrial, medical, and telecom applications (non-automotive, PPAP: No).
