GUS-QS8A-03-8661-FA Description

The GUS-QS8A-03-8661-FA is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for demanding surface-mount applications. With a resistance value of 8.66KΩ and a tight 1% tolerance, this component ensures reliable performance in precision circuits. The QSOP-16 package with gull-wing terminations offers a compact footprint (4.9mm × 6.02mm × 1.47mm), making it ideal for space-constrained PCB designs. Rated for 0.75W total power dissipation (0.1W per resistor) and operating over a -55°C to +125°C range, it excels in environments requiring stability under thermal stress. Its ±25ppm/°C temperature coefficient further enhances accuracy in temperature-variable conditions.
