GUS-QS8A-02-3920-CA Description

The GUS-QS8A-02-3920-CA 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 (QSOP-16) package, this isolated resistor array offers a 392Ω resistance per element with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it combines high power handling with precision in a miniaturized 4.9mm × 6.02mm × 1.47mm footprint. The gull-wing termination ensures reliable solderability for automated PCB assembly.
