GUS-QS0B-03-1802-FD Description

The GUS-QS0B-03-1802-FD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 18K Ohm resistance and a tight 1% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a 70°C to 125°C operating range, making it suitable for demanding environments. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its robustness. Packaged in a gull-wing QSOP case, it offers compact dimensions (8.66mm x 6.02mm x 1.47mm) with tight tolerances (±0.1mm height/length, ±0.2mm depth), ideal for space-constrained PCB designs.
