GUS-QS8A-02-2611-GB Description

The GUS-QS8A-02-2611-GB is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications requiring stable resistance values and compact packaging. This 16-pin QSOP device features 8 isolated resistors, each with a 2.61KΩ resistance (2% tolerance) and a ±50ppm/°C temperature coefficient, ensuring reliable 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 balances power handling with space efficiency, making it ideal for densely populated PCBs. The gull-wing termination and 0.64mm terminal pitch facilitate easy surface-mount assembly, while the 1.47mm low-profile height suits space-constrained designs.

GUS-QS8A-02-2611-GB Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, eliminating crosstalk.
• Robust Power Handling: 0.75W total power (0.1W per resistor) with derated performance up to 125°C.
• Compact QSOP Package: 4.9mm × 6.02mm footprint and 1.63mm seated height optimize board space.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its 100V maximum voltage rating suits industrial and consumer applications.
• Non-RoHS Compliance: Note: Not compliant with EU RoHS directives.
