GUS-QS8B-03-2870-B Description

The GUS-QS8B-03-2870-B 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 287Ω resistance value, offering a tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of 70°C to 125°C. The gull-wing termination ensures secure PCB mounting, while the compact 4.9mm x 6.02mm x 1.47mm footprint suits space-constrained designs.
