GUS-QS8A-03-7500-JF Description

The GUS-QS8A-03-7500-JF from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision surface-mount applications. Built with thin-film technology, it offers a 750Ω resistance per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. The device is housed in a compact 16-pin QSOP package with gull-wing terminations, making it ideal for automated PCB assembly. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it balances power handling and space efficiency. The non-automotive, non-PPAP compliant part is supplied in tubes for ease of handling.

GUS-QS8A-03-7500-JF Features

• High Precision: Thin-film construction ensures low TCR (±25ppm/°C) and tight 5% tolerance for reliable signal conditioning.
• Robust Power Handling: 0.75W total power dissipation (0.1W per resistor) supports demanding circuits.
• Compact Form Factor: QSOP-16 package (4.9mm × 6.02mm × 1.47mm) with 0.64mm pitch saves board space.
• Wide Temperature Range: Operates from -70°C to +125°C, suitable for industrial environments.
• Isolated Design: Independent resistors (ISOL circuit designator) allow flexible circuit configurations.
• Surface-Mount Ready: Gull-wing terminations ensure secure soldering and compatibility with reflow processes.
