GUS-QS8A-03-2870-GA Description

The GUS-QS8A-03-2870-GA is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications requiring stable resistance and tight tolerances. This 8-resistor isolated network features a 287Ω resistance value per resistor with a 2% tolerance and an ultra-low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating temperatures. Encased in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) ideal for space-constrained PCB designs. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably in environments ranging from 70°C to 125°C. The non-automotive, non-PPAP compliant device is supplied in tubes, catering to industrial and commercial applications.
