GUS-QS8A-03-4642-GB Description

The GUS-QS8A-03-4642-GB is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications requiring stable resistance values and tight tolerances. This 8-resistor isolated network features a 46.4KΩ resistance per element 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, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) with gull-wing SMD termination, making it ideal for space-constrained PCB designs. Rated for 0.75W total power dissipation (0.1W per resistor) and 100V maximum voltage, it operates reliably from 70°C to 125°C, with a derated power range extending to 125°C.
