GUS-QS8A-02-1271-BB Description

The GUS-QS8A-02-1271-BB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 1.27 kΩ resistance, offering 0.1% tolerance and an ultra-stable ±50 ppm/°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 70°C to 125°C, derated for optimal performance. The gull-wing termination ensures secure PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs. Its 100V maximum voltage rating and thin-film technology provide exceptional accuracy and long-term stability, making it ideal for precision analog and digital circuits.
