GUS-QS8A-03-2800-CB Description

The GUS-QS8A-03-2800-CB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull wing terminations, this isolated network offers a 280Ω resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 0.1W (1/10W) per resistor and 0.75W (3/4W) total power dissipation, it operates reliably across a wide temperature range of 70°C to 125°C (derated) and withstands up to 125°C maximum ambient temperature. Its 100V maximum voltage rating and thin film technology ensure stable performance in precision circuits.

GUS-QS8A-03-2800-CB Features
