GUS-QS8A-02-75R0-DD Description

The GUS-QS8A-02-75R0-DD from TT Electronics/IRC is a high-precision 8-resistor isolated network designed for demanding surface-mount applications. This thin-film resistor array offers a 75Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP package with gull-wing leads, it features 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 eliminates crosstalk between resistors, critical for precision signal conditioning.
