GUS-QS8A-02-1331-CA Description

The GUS-QS8A-02-1331-CA 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 1.33KΩ resistance value with an ultra-tight 0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -55°C to +125°C. Packaged in a 16-pin QSOP with gull-wing terminations, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) 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 100V maximum voltage rating, it balances performance and reliability in precision circuits.
