GUS-QS0B-03-1132-D Description

The GUS-QS0B-03-1132-D from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 11.3KΩ resistance value per resistor with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. Housed in a 20-pin QSOP package with gull-wing terminations, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch for high-density PCB layouts. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it combines precision with robustness.

GUS-QS0B-03-1132-D Features
