GUS-QS0B-03-3920-J Description

The GUS-QS0B-03-3920-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 19-resistor array features a 392Ω resistance value per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a compact 20-pin QSOP package with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for densely packed circuits requiring reliable power dissipation. The thin-film technology provides superior accuracy and long-term stability compared to thick-film alternatives.
