GUS-QS0B-03-3920-GF Description

The GUS-QS0B-03-3920-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 19-resistor network features a 392Ω resistance value per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 20-pin QSOP (QSOP) package with gull-wing SMD termination, it offers a compact footprint (8.66mm x 6.02mm x 1.47mm) and robust 1W total power dissipation (0.05W per resistor). Ideal for surface-mount assembly, it supports 100V maximum voltage rating and is supplied in tube packaging for automated handling.
