GUS-QS8A-02-45R3-DD Description

The GUS-QS8A-02-45R3-DD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a compact QSOP-16 package with gull-wing terminations, offering a 45.3 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 dissipation and 0.1W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, with a maximum voltage rating of 100V. Its isolated circuit design (ISOL) ensures independent resistor performance, making it ideal for precision analog and digital circuits.

GUS-QS8A-02-45R3-DD Features
