GUS-QS8A-02-1690-DD Description

The GUS-QS8A-02-1690-DD 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 package with gull wing terminations, this isolated resistor array offers a 169 Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±50 ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power (0.1W per resistor), it operates reliably across a wide temperature range of -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.
