GUS-QS0B-02-4121-BB Description

The GUS-QS0B-02-4121-BB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 4.12KΩ resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. 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). The 100V maximum voltage rating and thin-film technology provide superior accuracy and reliability for precision circuits. Non-automotive and non-RoHS compliant, it is supplied in tube packaging for ease of handling.
