GUS-QS8A-02-29R4-FF Description

The GUS-QS8A-02-29R4-FF from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a compact 16-pin QSOP package with gull wing termination, this 29.4Ω network offers 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C derated power range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it excels in demanding environments. The isolated (ISOL) circuit design enhances flexibility, while its surface-mountable form factor (4.9mm × 6.02mm × 1.47mm) suits high-density PCB layouts.

GUS-QS8A-02-29R4-FF Features

• Precision Thin Film Technology: Delivers superior accuracy (±1%) and stability (±50ppm/°C) for critical circuits.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) outperforms standard networks in thermal management.
• Isolated Design (ISOL): Independent resistors enable versatile circuit configurations without crosstalk.
• Robust Construction: QSOP package with gull wing leads ensures reliable solder joints and mechanical durability.
• Wide Temperature Range: Operates from -55°C to +125°C (derated power up to 125°C), ideal for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Compact Footprint: 4.9mm × 6.02mm profile with 1.63mm seated height optimizes space-constrained designs.
