GUS-QS0B-03-1821-FD Description

The GUS-QS0B-03-1821-FD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 1.82KΩ resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a compact 20-pin QSOP package with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs. The 8.66mm × 6.02mm × 1.47mm footprint and ±0.1mm dimensional tolerances ensure reliable placement in automated assembly processes.

GUS-QS0B-03-1821-FD Features
