GUS-QS8A-03-4300-CA Description

The GUS-QS8A-03-4300-CA from TT Electronics/IRC is a high-precision 8-resistor isolated network designed for demanding surface-mount applications. Built with thin-film technology, it offers a 430Ω resistance per resistor with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. Housed in a 16-pin QSOP package with gull-wing terminations, this network delivers 0.1W (1/10W) power dissipation per resistor and a total power rating of 0.75W (3/4W), making it suitable for high-density PCB designs. Its 100V maximum voltage rating and isolated (ISOL) circuit design enhance reliability in precision analog and digital circuits.
