GUS-QS8A-02-9102-FB Description

The GUS-QS8A-02-9102-FB is a high-performance 8-resistor isolated network from TT Electronics/IRC, designed for precision applications in surface-mount PCB assemblies. This thin-film resistor network offers a 91kΩ resistance value per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP (QSOP-16) package with gull-wing terminations, it features a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-density designs requiring reliable power dissipation and signal integrity.

GUS-QS8A-02-9102-FB Features

• Precision Thin Film Technology: Delivers superior accuracy (±1%) and low TCR (±50ppm/°C) for stable performance in varying thermal conditions.
• Isolated Circuit Design (ISOL): Each resistor is electrically isolated, enabling flexible circuit configurations without crosstalk.
• Compact QSOP-16 Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained applications.
• High Power Handling: 0.75W total power rating (0.1W per resistor) outperforms similar networks in its class.
• Robust Construction: Gull-wing SMD terminations with 0.64mm pitch ensure reliable solder joints and mechanical durability.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, suitable for industrial and automotive environments (though not PPAP/AEC-Q200 qualified).
