GUS-QS8A-03-1051-DA Description

The GUS-QS8A-03-1051-DA 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 1.05KΩ resistance value per resistor with an ultra-tight ±0.5% 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, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) while delivering 0.1W (1/10W) power dissipation per resistor and a total power rating of 0.75W (3/4W). Its 100V maximum voltage rating and thin-film technology make it ideal for precision analog and digital circuits.
