GUS-QS8A-02-2701-DB Description

The GUS-QS8A-02-2701-DB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. This 16-pin QSOP package features 8 isolated resistors, each with a 2.7KΩ resistance, 0.5% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable power handling in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the 1.47mm low-profile height suits space-constrained applications.

GUS-QS8A-02-2701-DB Features

• Precision Thin Film Technology: Offers superior accuracy (±0.5%) and low TCR (±50ppm/°C) for stable signal conditioning.
• Isolated Resistor Network (ISOL): Each of the 8 resistors is electrically isolated, enabling flexible circuit design.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) at 125°C, derated for high-temperature operation.
• Compact QSOP Package: 4.9mm x 6.02mm footprint with 1.63mm seated height, ideal for dense PCB layouts.
• High Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation applications.
• Gull-Wing SMD Termination: Ensures reliable solder joints and compatibility with automated assembly processes.
