GUS-QS0B-03-2611-DD Description

The GUS-QS0B-03-2611-DD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 2.61KΩ 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 20-pin QSOP package with gull-wing terminations, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and robust 1W total power dissipation (0.05W per resistor). Rated for 100V maximum voltage, it is ideal for precision analog and digital circuits requiring matched resistance values.
