GUS-QS8A-02-1743-BA Description

The GUS-QS8A-02-1743-BA is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding applications requiring tight tolerances and stable performance. This 8-resistor isolated network features a 174K Ohm resistance value with an exceptional 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed 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 within a -55°C to +125°C temperature range. The non-automotive, non-PPAP compliant device is supplied in a tube packaging for efficient handling.
