GUS-QS8A-03-1543-BB Description

The GUS-QS8A-03-1543-BB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. This 8-resistor isolated network features a 154K Ohm resistance value with an ultra-tight 0.1% 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 16-pin QSOP package with gull-wing terminations, it offers a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height) and a 0.64mm terminal pitch, making it ideal for high-density PCB designs. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this non-automotive, non-PPAP compliant component is RoHS non-compliant and supplied in tube packaging.
