GUS-QS0B-03-2671-B Description

The GUS-QS0B-03-2671-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 20-pin QSOP surface-mount device integrates 19 resistors with a uniform 2.67KΩ resistance value, offering 0.1% tolerance and an ultra-low ±25ppm/°C temperature coefficient. With a 1W 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 8.66mm × 6.02mm × 1.47mm footprint suits space-constrained designs.
