GUS-QS8A-03-3300-CB Description

The GUS-QS8A-03-3300-CB 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 330Ω resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°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 terminations, 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, enhancing signal integrity.
