GUS-QS8A-03-4750-CA Description

The GUS-QS8A-03-4750-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 475Ω resistance value 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 SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) while delivering 0.75W (3/4W) total power dissipation and 0.1W per resistor. Rated for 100V maximum voltage, this non-automotive, non-PPAP component is ideal for precision analog and digital circuits requiring high reliability.
