GUS-QS0B-03-2872-FD Description

The GUS-QS0B-03-2872-FD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 28.7KΩ resistance value, a tight 1% tolerance, and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a 0.05W (1/20) power rating per resistor and a total power rating of 1W, this network is optimized for compact, high-density PCB designs. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable soldering in automated assembly processes. The 8.66mm × 6.02mm × 1.47mm form factor and ±0.1mm dimensional tolerances ensure consistent placement accuracy.
