GUS-QS0B-03-8872-G Description

The GUS-QS0B-03-8872-G 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 88.7KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a ±25ppm/°C temperature coefficient, it delivers excellent 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 high-reliability designs. Its gull-wing termination and compact 8.66mm x 6.02mm x 1.47mm footprint enable efficient PCB space utilization.
