GUS-QS8A-02-6190-DA Description

The GUS-QS8A-02-6190-DA 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 device offers an isolated configuration (ISOL) with a 619Ω resistance per element, tight 0.5% tolerance, and a low ±50ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power (0.1W per resistor), it operates reliably across a -55°C to +125°C range, with derated performance up to 125°C. Its 100V maximum voltage rating and thin film technology ensure stable performance in precision circuits.
