GUS-QS0B-03-4122-DC Description

The GUS-QS0B-03-4122-DC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 41.2KΩ resistance, a tight 0.5% tolerance, and a low ±25ppm/°C temperature coefficient. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C. Its gull-wing termination and 0.64mm pitch ensure compatibility with automated PCB assembly processes. The non-automotive, non-PPAP compliant device is supplied in a tube packaging, making it suitable for prototyping and medium-volume production.
