GUS-QS8A-03-8871-CA Description

The GUS-QS8A-03-8871-CA from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding surface-mount applications. With a resistance value of 8.87KΩ and an ultra-tight tolerance of 0.25%, this component ensures exceptional accuracy in signal conditioning, voltage division, and impedance matching circuits. Housed in a 16-pin QSOP package, it features gull-wing termination for reliable soldering in automated PCB assembly. The device operates across a wide temperature range of -70°C to +125°C, making it suitable for industrial and instrumentation environments. Its low TCR of ±25ppm/°C minimizes resistance drift under thermal stress, while the 100V maximum voltage rating and 0.75W total power dissipation enhance robustness in high-density designs.
