GUS-QS8A-03-3090-BA Description

The GUS-QS8A-03-3090-BA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. With a 309Ω resistance value and an ultra-tight 0.1% tolerance, this component ensures exceptional accuracy in signal conditioning, voltage division, and impedance matching. Housed in a compact 16-pin QSOP (QSOP) package, it features gull-wing termination for reliable soldering and mechanical stability. The device operates across a wide temperature range of -70°C to +125°C, making it suitable for industrial and instrumentation use. Its ±25ppm/°C temperature coefficient guarantees minimal resistance drift under thermal stress, while the 100V maximum voltage rating and 0.75W total power dissipation enhance robustness in high-density circuits.
