GUS-QS8A-03-1302-CB Description

The GUS-QS8A-03-1302-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 8-resistor isolated network features a 13KΩ resistance value per resistor with an exceptional ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a 16-pin QSOP (QSOP-16) package, it offers a compact 4.9mm × 6.02mm footprint with gull-wing SMD termination, making it ideal for space-constrained PCB designs. Rated for 0.1W (1/10W) per resistor and 0.75W (3/4W) total power dissipation, it operates reliably up to 125°C, with derated performance from 70°C to 125°C.
