GUS-QS8A-03-1072-BA Description

The GUS-QS8A-03-1072-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 8-resistor isolated network features a 10.7KΩ resistance value with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a compact 16-pin QSOP package with gull-wing terminations, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and operates reliably within a -70°C to +125°C derated power range, with a maximum operating temperature of 125°C. Its 100V maximum voltage rating and surface-mount design make it suitable for densely populated PCBs.
