GUS-QS0B-02-1500-DB Description

The GUS-QS0B-02-1500-DB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 19-resistor network features a compact QSOP-20 package with gull-wing terminations, offering a 150Ω resistance per element at an ultra-tight ±0.5% tolerance and ±50ppm/°C temperature coefficient. With a 1W total power rating (0.05W per resistor) and 100V maximum voltage rating, it operates reliably across a wide temperature range of -70°C to +125°C. The device is housed in a rectangular, tube-packaged form factor, measuring 8.66mm (L) × 6.02mm (D) × 1.47mm (H), making it ideal for space-constrained PCB designs.
