GUS-QS8A-03-61R9-GD Description

The GUS-QS8A-03-61R9-GD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 61.9 Ω resistance value with a tight 2% tolerance and an ultra-stable ±25 ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing SMD termination, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a maximum voltage rating of 100V. Its thin-film technology provides superior accuracy, low noise, and excellent long-term stability compared to thick-film alternatives.

GUS-QS8A-03-61R9-GD Features

• Precision Thin Film: Delivers high accuracy (±2%) and low TCR (±25 ppm/°C) for stable operation in demanding environments.
• Compact & Robust: QSOP-16 package (4.9mm x 6.02mm x 1.47mm) with 0.64mm terminal pitch, ideal for space-constrained PCB designs.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• High Power Handling: 0.75W total power dissipation (0.1W per resistor) at 125°C maximum operating temperature.
• Surface-Mount Gull Wing Termination: Ensures reliable solder joints and compatibility with automated assembly processes.
• Non-Automotive, Non-PPAP: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
