GUS-QS8A-02-2740-GB Description

The GUS-QS8A-02-2740-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 8 isolated resistors, each with a 274Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of 70°C to 125°C, derated for optimal thermal management. The device features a ±50ppm/°C temperature coefficient, minimizing resistance drift under thermal stress, and supports 100V maximum voltage rating, making it suitable for both analog and digital signal conditioning.

GUS-QS8A-02-2740-GB Features

• Precision Thin Film Technology: Delivers stable resistance with low noise and high accuracy.
• Isolated Resistor Network (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• Robust Construction: QSOP package with gull-wing terminals (0.64mm pitch) ensures reliable surface-mount soldering.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) outperforms standard networks in compact designs.
• Extended Temperature Range: Operates up to 125°C with derated power, suited for industrial environments.
• Non-Automotive (PPAP No): Optimized for commercial and industrial applications where PPAP compliance isn’t required.
