GUS-QS8A-03-1432-DB Description

The GUS-QS8A-03-1432-DB is a high-precision 8-resistor thin-film network from TT Electronics/IRC, designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull-wing terminations, it offers a 14.3KΩ resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C. Its 100V maximum voltage rating and isolated (ISOL) circuit design make it suitable for precision analog and digital circuits.
