GUS-QS0B-03-6341-FB Description

The GUS-QS0B-03-6341-FB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. This 19-resistor array features a 6.34KΩ resistance value with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a compact 20-pin QSOP package with gull-wing terminations, it offers a 0.64mm terminal pitch and a 1.63mm seated height, making it ideal for space-constrained PCB designs. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in precision analog and digital circuits.
