GUS-QS8A-03-2262-CB Description

The GUS-QS8A-03-2262-CB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull wing termination, this device offers a 22.6KΩ resistance per resistor with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for precision signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of -55°C to +125°C, derated from 70°C to 125°C. The compact 4.9mm × 6.02mm × 1.47mm footprint and 1.63mm seated height enable high-density PCB layouts.
