GUS-QS0B-02-3090-B Description

The GUS-QS0B-02-3090-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 309Ω 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 a 1W total power rating (0.05W per resistor). Its 100V maximum voltage rating and thin-film technology make it ideal for precision analog and digital circuits.
