GUS-QS0B-02-1052-B Description

The GUS-QS0B-02-1052-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 10.5KΩ resistance value per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Housed in a compact 20-pin QSOP package with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and supports 100V maximum voltage. Its rectangular, tube-packaged design (8.66mm × 6.02mm × 1.47mm) adheres to strict dimensional tolerances (±0.1mm height/length, ±0.2mm depth), making it ideal for space-constrained PCBs.
