GUS-QS8A-02-3740-DB Description

The GUS-QS8A-02-3740-DB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Housed in a compact 16-pin QSOP package with gull wing terminals, this isolated resistor array offers a 374Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably across a wide temperature range (-70°C to +125°C), making it suitable for harsh environments. The 100V maximum voltage rating and thin film technology ensure stable performance in precision circuits.
