GUS-QS8A-02-1473-BA Description

The GUS-QS8A-02-1473-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 network features a 147K Ohm resistance value with an exceptional 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. 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. Rated for 0.75W (3/4W) total power dissipation and 0.1W per resistor, it operates reliably within a -55°C to +125°C range, derated from 70°C to 125°C. The isolated (ISOL) circuit design enhances signal integrity, while a 100V maximum voltage rating suits medium-voltage applications.
