GUS-QS8A-03-1800-GD Description

The GUS-QS8A-03-1800-GD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount circuits. This 8-resistor isolated network features a 180Ω resistance value per resistor with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP (QSOP) package, it offers a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, making it suitable for densely populated PCBs. The gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and automated assembly.

GUS-QS8A-03-1800-GD Features

• Precision Thin Film Technology: Delivers low noise, high stability, and excellent TCR performance.
• Isolated Circuit Design (ISOL): Each resistor operates independently, ideal for signal isolation.
• Robust Power Handling: 0.75W total power (0.1W per resistor) with derating up to 125°C.
• Compact & Durable: 4.9mm (L) x 6.02mm (D) x 1.47mm (H) footprint with a 1.63mm seated height, optimized for space-constrained designs.
• High Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation applications.
• Surface-Mount Ready: Gull-wing leads and 0.64mm pitch ensure compatibility with standard SMD processes.

GUS-QS8A-03-1800-GD Applications
