GUS-QS8A-03-9092-CA Description

The GUS-QS8A-03-9092-CA 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 90.9KΩ resistance value with an exceptional ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across its operating range. Encased in a compact 16-pin QSOP package with gull-wing SMD termination, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and operates reliably from 70°C to 125°C derated, with a maximum operating temperature of 125°C. Its 100V maximum voltage rating and thin-film technology provide superior accuracy and long-term stability in precision circuits.
