GUS-QS0B-03-1911-FB Description

The GUS-QS0B-03-1911-FB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 1.91KΩ resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 20-pin QSOP package with gull-wing terminals, it offers a 0.64mm pitch for high-density PCB layouts. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is ideal for precision analog and digital circuits. The non-automotive, non-PPAP compliant device is supplied in tubes for efficient handling.
