GUS-QS8A-03-2871-BA Description

The GUS-QS8A-03-2871-BA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding applications requiring tight tolerances and stable performance. With a 2.87KΩ resistance value and an exceptional ±0.1% tolerance, this component ensures reliable signal integrity in precision circuits. Packaged in a 16-pin QSOP with gull wing terminations, it offers a compact 4.9mm × 6.02mm footprint, making it ideal for space-constrained surface-mount (SMD) designs. Its thin film technology provides a low ±25ppm/°C temperature coefficient, ensuring minimal drift across the -70°C to +125°C operating range. Rated for 100V maximum voltage and 0.75W total power dissipation, it balances performance with robustness.
