GUS-QS8A-02-6810-JA Description

The GUS-QS8A-02-6810-JA from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications in surface-mount PCB assemblies. Encased in a 16-pin QSOP package with gull wing terminations, this 681Ω ±5% resistor network delivers a 0.75W (3/4W) total power rating and operates across a wide temperature range of -70°C to +125°C. Its thin film technology ensures low noise and excellent stability, with a tight ±50ppm/°C temperature coefficient, making it ideal for circuits requiring consistent performance under thermal stress. The isolated (ISOL) circuit design allows flexible configuration, while the 100V maximum voltage rating and 0.1W per-resistor derating ensure reliability in demanding environments.

GUS-QS8A-02-6810-JA Features

• Precision Thin Film: Offers superior accuracy (±5%) and low TCR (±50ppm/°C) for stable signal conditioning.
• Robust Construction: QSOP package with gull wing leads ensures secure surface mounting and mechanical durability.
• High Power Handling: 0.75W total power dissipation (0.1W per resistor) supports energy-intensive applications.
• Wide Operating Range: Functions reliably from -70°C to +125°C, suitable for industrial and automotive-adjacent systems (though not PPAP/automotive-certified).
• Isolated Design: Independent resistors enable versatile circuit integration without cross-talk.
• Compact Dimensions: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length) for high-density layouts.
