GUS-QS8A-03-84R5-FD Description

The GUS-QS8A-03-84R5-FD 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 resistance value of 84.5Ω at a tight 1% tolerance and a low ±25ppm/°C temperature coefficient. With a power rating of 0.75W (3/4W) total and 0.1W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for precision circuits in harsh environments. The 100V maximum voltage rating and thin-film technology ensure stable performance in high-accuracy applications.

GUS-QS8A-03-84R5-FD Features

• High Precision: 1% tolerance and ±25ppm/°C TCR for stable performance in precision analog/digital circuits.
• Robust Construction: Thin-film technology ensures low noise, high stability, and long-term reliability.
