GUS-QS0B-03-1052-JB Description

The GUS-QS0B-03-1052-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package integrates 19 resistors, each with a 10.5K Ohm resistance and a 5% tolerance, delivering a ±25ppm/°C temperature coefficient for stable operation across a 70 to 125°C derated power range. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this surface-mount device (SMD) is ideal for compact, high-density PCB designs. Its gull-wing termination ensures reliable solder joints, while the 6.02 x 8.66 x 1.47mm footprint balances space efficiency with thermal performance.
