GUS-QS8A-03-91R0-GF Description

The GUS-QS8A-03-91R0-GF from TT Electronics/IRC is a high-performance 8-resistor isolated thin film network designed for precision applications. Encased in a 16-pin QSOP package with gull-wing SMD termination, it offers a 91Ω resistance per resistor with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. Rated for 0.1W (1/10W) power dissipation per resistor and 0.75W (3/4W) total power, it operates reliably across a wide temperature range of -70°C to +125°C, with a maximum voltage rating of 100V. Its compact dimensions (4.9mm x 6.02mm x 1.47mm) and 0.64mm terminal pitch make it ideal for space-constrained PCB designs.

GUS-QS8A-03-91R0-GF Features

• Thin Film Technology: Delivers superior stability, low noise, and precision compared to thick-film alternatives.
• Isolated Circuit Design (ISOL): Each resistor operates independently, enhancing flexibility in circuit design.
• High Power Density: 0.75W total power rating in a miniature QSOP package, optimizing board space.
• Wide Operating Range: Performs reliably from -70°C to +125°C, suitable for industrial and automotive derating conditions.
• Robust Construction: Gull-wing leads ensure secure surface mounting, while the tube packaging protects during handling.
• Non-Automotive/Non-PPAP: Ideal for commercial and industrial applications where PPAP compliance is not required.
