GUS-QS8A-02-7500-JA Description

The GUS-QS8A-02-7500-JA from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision surface-mount applications. Built with thin-film technology, it offers a 750Ω resistance value per resistor with a 5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. The device is housed in a compact 16-pin QSOP package with gull-wing terminations, optimized for automated PCB assembly. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling and space efficiency. The isolated circuit design (ISOL) allows independent resistor operation, making it ideal for signal conditioning and voltage division in demanding environments.
