GUS-QS8A-02-8251-BB Description

The GUS-QS8A-02-8251-BB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. This QSOP-packaged device features an 8.25KΩ resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C derated power range. With a 100V maximum voltage rating and 0.75W (3/4W) total power dissipation, it combines reliability with compact dimensions (4.9mm x 6.02mm x 1.47mm). The 16-pin gull-wing termination and 0.64mm pitch facilitate automated PCB assembly, while its isolated (ISOL) circuit design enhances flexibility in circuit configurations.

GUS-QS8A-02-8251-BB Features

• Precision Thin Film Technology: Delivers 0.1% tolerance and ±50ppm/°C TCR for critical analog/digital circuits.
• Robust Power Handling: 0.1W per resistor (0.75W total) at 125°C max operating temperature, ideal for thermally constrained designs.
• Compact QSOP Package: Space-saving 16-pin profile with 1.63mm seated height, suited for high-density PCBs.
• Isolated Network (ISOL): Independent resistors enable versatile biasing, feedback, or termination applications.
