GUS-QS8A-02-7502-DB Description

The GUS-QS8A-02-7502-DB is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for demanding surface-mount applications. It features a 75kΩ resistance value per resistor with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C derated, 125°C max). Housed 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 a 100V maximum voltage rating. Its isolated (ISOL) circuit design and thin-film technology provide superior accuracy and reliability compared to thick-film alternatives.
