GUS-QS8A-03-4702-BA Description

The GUS-QS8A-03-4702-BA 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 47K Ohm resistance with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring exceptional stability 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 offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it ideal for precision analog and digital circuits. The isolated (ISOL) circuit design enhances signal integrity by minimizing crosstalk between channels.
