GUS-QS8A-03-2800-DB Description

The GUS-QS8A-03-2800-DB from TT Electronics/IRC is a high-precision 8-resistor isolated network designed for demanding surface-mount applications. This 280Ω thin-film resistor array features a tight 0.5% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). Housed in a compact 16-pin QSOP package with gull-wing terminations, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs. The isolated (ISOL) circuit design allows independent resistor operation, enhancing flexibility in circuit configurations.

GUS-QS8A-03-2800-DB Features
