GUS-QS0B-02-1101-DA Description

The GUS-QS0B-02-1101-DA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 1.1KΩ resistance value per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Housed in a 20-pin QSOP package with gull-wing terminations, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch for high-density PCB layouts. Rated for 100V maximum voltage and 1W total power dissipation (0.05W per resistor), it combines precision with robustness.
