GUS-QS8A-03-3480-GF Description

The GUS-QS8A-03-3480-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device features 8 isolated resistors, each with a 348Ω resistance value and a tight 2% tolerance. With a ±25ppm/°C temperature coefficient, it ensures stable performance across a wide temperature range of -70°C to +125°C. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the tube packaging ensures safe handling and storage.

GUS-QS8A-03-3480-GF Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): Each of the 8 resistors operates independently, eliminating crosstalk.
• Robust Power Handling: 0.75W total power dissipation (0.1W per resistor) with derating up to 125°C.
• Compact QSOP Package: Measures just 4.9mm (L) x 6.02mm (D) x 1.47mm (H), ideal for space-constrained designs.
• Wide Operating Range: Performs reliably from -70°C to +125°C, suited for industrial and automotive environments (though not PPAP/AEC-Q200 qualified).
• High Voltage Tolerance: Supports up to 100V, making it versatile for power supply and signal conditioning applications.
