GUS-QS8B-03-3920-C Description

The GUS-QS8B-03-3920-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP (Quarter-Small Outline Package) device integrates 15 resistors with a 392Ω resistance value, offering a tight tolerance of ±0.25% and a low temperature coefficient of ±25ppm/°C. With a 0.75W (3/4W) total power rating (0.05W per resistor), it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for industrial and instrumentation environments. The gull-wing termination ensures secure PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint optimizes board space.
