GUS-QS8A-03-2370-BA Description

The GUS-QS8A-03-2370-BA is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding applications requiring tight tolerances and stable performance. This 8-resistor isolated network features a 237Ω resistance value per resistor with an exceptional 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a 16-pin QSOP (QSOP) package, it offers a compact 4.9mm × 6.02mm footprint with a 1.47mm profile, ideal for space-constrained surface-mount (SMD) designs. Rated for 0.75W (3/4W) total power dissipation and 0.1W per resistor, it operates reliably across a 70°C to 125°C derated range, with a maximum 125°C operating temperature. The 100V maximum voltage rating and gull-wing termination enhance durability in high-density PCB layouts.
