GUS-QS0B-03-8661-FD Description

The GUS-QS0B-03-8661-FD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors with a 8.66KΩ resistance value, offering 1% tolerance and a ±25ppm/°C temperature coefficient for stable performance across a -70°C to +125°C operating range. With a 1W total power rating (0.05W per resistor) and 100V maximum voltage rating, it excels in compact, high-density circuits requiring reliable signal conditioning or voltage division. The gull-wing termination ensures secure PCB mounting, while the tube packaging facilitates automated assembly.
