GUS-QS8B-03-1911-D Description

The GUS-QS8B-03-1911-D from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP device integrates 15 resistors with a 1.91KΩ resistance value, offering a tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, it ensures reliable performance in high-density circuits. The gull-wing termination and QSOP package (4.9mm x 6.02mm x 1.47mm) facilitate automated assembly, while its -70°C to +125°C operating range suits industrial environments.

GUS-QS8B-03-1911-D Features

• Precision Thin Film Technology: Delivers stable performance with low TCR (±25ppm/°C) and tight tolerance (±0.5%).
• Robust Power Handling: 0.75W total dissipation (0.05W per resistor) at 125°C maximum temperature.
• Compact QSOP Package: Space-saving 16-pin gull-wing SMD design (6.02mm depth, 1.47mm height) with ±0.1mm height/length tolerances.
• High Voltage Rating: Supports up to 100V, ideal for analog and mixed-signal circuits.
• Automation-Friendly: Tube packaging ensures compatibility with pick-and-place systems.
• Non-Automotive/Non-PPAP: Suitable for industrial and commercial applications where PPAP compliance is not required.
