GUS-QS8A-02-6342-BB Description

The GUS-QS8A-02-6342-BB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter Small Outline Package) device features eight isolated 63.4kΩ resistors with an ultra-tight tolerance of ±0.1% and a low temperature coefficient of ±50ppm/°C, ensuring exceptional stability across a wide operating range of -70°C to +125°C. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable performance in compact, space-constrained designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy surface-mount assembly, while the 1.47mm low-profile height makes it suitable for high-density PCB layouts.
