GUS-QS0B-03-1872-GF Description

The GUS-QS0B-03-1872-GF from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a compact 20-pin QSOP package with gull-wing terminations, ensuring reliable PCB mounting. With a resistance value of 18.7KΩ (±2% tolerance) and a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C derated, 125°C max). Rated for 1W total power dissipation (0.05W per resistor), it supports 100V maximum voltage, making it suitable for precision analog and digital circuits. The non-automotive, non-PPAP compliant device is supplied in tubes, ideal for prototyping and volume production.
