GUS-QS8A-02-3090-GA Description

The GUS-QS8A-02-3090-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 309Ω resistance and a tight 2% tolerance, ensuring reliable signal conditioning and voltage division. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of -70°C to +125°C. The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for demanding environments. Packaged in a gull-wing QSOP format, it offers excellent solderability and space efficiency for compact PCB designs.

GUS-QS8A-02-3090-GA Features

• Precision Thin Film Technology: Ensures low noise, high stability, and tight resistance tolerances (±2%).
• High Power Handling: 0.1W per resistor (0.75W total) with derating up to 125°C.
• Wide Temperature Range: Reliable operation from -70°C to +125°C, ideal for industrial and automotive-grade applications (though not PPAP/automotive certified).
• Compact QSOP Package: 4.9mm x 6.02mm footprint with 1.47mm profile, optimized for high-density layouts.
• Isolated Resistors (ISOL): Independent 309Ω resistors reduce crosstalk in signal paths.
• Robust Construction: Gull-wing terminals with 0.64mm pitch for secure SMD mounting.
• Non-RoHS Compliant: Suitable for legacy or specialized systems requiring leaded components.
