GUS-QS8A-02-3570-BA Description

The GUS-QS8A-02-3570-BA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull wing termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) and a 357Ω resistance per resistor with an ultra-tight 0.1% tolerance. The device operates over a wide temperature range (-70°C to +125°C) and delivers a 0.75W (3/4W) total power rating, with 0.1W per resistor. Its ±50ppm/°C temperature coefficient ensures stability in thermally dynamic environments, while the 100V maximum voltage rating and isolated (ISOL) circuit design enhance reliability in precision circuits.
