GUS-QS0B-03-3480-GF Description

The GUS-QS0B-03-3480-GF from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 348Ω resistance value per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a compact 20-pin QSOP (QSOP) package with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and a maximum voltage rating of 100V. The device is non-automotive and non-PPAP compliant, making it ideal for industrial and commercial electronics.
