GUS-QS0B-03-6191-GF Description

The GUS-QS0B-03-6191-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 6.19KΩ resistance value and a tight 2% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of -70°C to +125°C. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Its gull-wing termination and compact 8.66mm × 6.02mm × 1.47mm footprint enable efficient PCB space utilization.
