GUS-QS8A-02-1333-BB Description

The GUS-QS8A-02-1333-BB 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 133K Ohm resistance with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70 to 125°C. Housed in a 16-pin QSOP package with gull wing terminals, it offers a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height) and a 0.64mm terminal pitch for high-density PCB layouts. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it combines precision with robust performance.
