GUS-QS8A-03-4020-BA Description

The GUS-QS8A-03-4020-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 402Ω resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) for space-constrained PCB designs. Rated for 0.75W total power dissipation (0.1W per resistor) and 100V maximum voltage, it operates reliably across a -55°C to +125°C range, with derated performance up to 125°C.
