GUS-QS0B-02-3000-B Description

The GUS-QS0B-02-3000-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 300Ω resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. Housed in a 20-pin QSOP package with gull-wing terminations, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and robust performance for high-density PCB designs. With a 1W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances power handling with precision.
