GUS-QS8A-02-1271-GB Description

The GUS-QS8A-02-1271-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 1.27KΩ resistance, 2% tolerance, and a ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of -55°C to +125°C, derated up to 125°C. Its gull-wing termination and 0.64mm terminal pitch ensure easy PCB integration, while the compact 4.9mm x 6.02mm x 1.47mm footprint suits space-constrained designs.
