GUS-QS0B-03-1801-GD Description

The GUS-QS0B-03-1801-GD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount assemblies. This 19-resistor array features a 1.8KΩ resistance value per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 20-pin QSOP package with gull-wing terminations, it offers a power rating of 1W (0.05W per resistor) and a maximum voltage rating of 100V, making it suitable for demanding circuit designs. The device is non-automotive and non-PPAP compliant, with a RoHS non-compliant status.

GUS-QS0B-03-1801-GD Features

• Precision Thin Film Technology: Delivers high accuracy (±2%) and low TCR (±25ppm/°C) for stable operation in varying thermal conditions.
• Compact QSOP Package: Measures 8.66mm (L) x 6.02mm (D) x 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D), ideal for space-constrained PCBs.
• High Power Handling: 1W total power dissipation (0.05W per resistor) at 125°C maximum operating temperature.
• Robust Construction: Gull-wing SMD terminations ensure reliable solder joints, while the tube packaging protects during handling and assembly.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation applications.
