GUS-QS8A-02-1131-GB Description

The GUS-QS8A-02-1131-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 1.13KΩ resistance value with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for high-density PCB designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable surface-mount assembly, while its 100V maximum voltage rating enhances durability in demanding circuits.

GUS-QS8A-02-1131-GB Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and long-term stability.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained applications.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• High Power Density: 0.75W total dissipation in a miniature footprint outperforms similar networks.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, TT Electronics offers variants for harsh environments.
