GUS-QS0B-02-5110-B Description

The GUS-QS0B-02-5110-B is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. This 19-resistor array features a 511Ω resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring exceptional stability across a wide operating temperature range of 70°C to 125°C. Housed in a compact 20-pin QSOP (QSOP) package with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and supports 100V maximum voltage. The rectangular package (8.66mm x 6.02mm x 1.47mm) is optimized for high-density PCB layouts, with tight tolerances (±0.1mm height/length, ±0.2mm depth).
