GUS-QS8A-03-6040-FB Description

The GUS-QS8A-03-6040-FB 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 604Ω resistance value and a tight 1% 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 stability. The device features a ±25ppm/°C temperature coefficient, minimizing resistance drift under thermal stress, and supports a maximum voltage rating of 100V. Its gull-wing termination and 0.64mm terminal pitch facilitate robust soldering in automated SMT processes.

GUS-QS8A-03-6040-FB Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Design (ISOL): Each of the 8 resistors operates independently, eliminating crosstalk in multi-channel systems.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained designs.
• High Power Density: 0.75W total dissipation in a miniature footprint outperforms similar networks in thermal management.
• Wide Operating Range: Functions from -55°C to +125°C, suitable for industrial and telecom environments.
• Non-Automotive (PPAP No): Optimized for commercial/industrial use, with EU RoHS non-compliance noted for specific legacy applications.
