GUS-QS8A-02-4870-FF Description

The GUS-QS8A-02-4870-FF from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications in demanding electronic circuits. Featuring a 487Ω resistance value with a tight 1% tolerance, this thin-film resistor network delivers exceptional stability and accuracy. Encased in a 16-pin QSOP (Quarter-Small Outline Package), it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) with gull-wing surface-mount terminals, ensuring reliable PCB integration. Rated for 0.75W total power dissipation (0.1W per resistor) and operating across a -55°C to +125°C temperature range, it excels in environments requiring robust thermal performance. Its ±50ppm/°C temperature coefficient minimizes resistance drift, while the 100V maximum voltage rating enhances durability in high-voltage circuits.
