GUS-QS8A-02-6801-JB Description

The GUS-QS8A-02-6801-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 8 isolated 6.8KΩ resistors with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in demanding circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density mounting.

GUS-QS8A-02-6801-JB Features

• High Precision: Thin-film technology delivers low TCR (±50ppm/°C) and tight tolerance (5%), ideal for signal conditioning and analog circuits.
• Robust Construction: QSOP package (4.9mm x 6.02mm x 1.47mm) with ±0.1mm length/height tolerances ensures mechanical stability.
• Isolated Resistors: 8 independent 6.8KΩ resistors (ISOL circuit designator) prevent crosstalk in multi-channel systems.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C, suitable for industrial and automotive environments (though not PPAP/automotive-certified).
• Surface-Mount Optimized: Gull-wing leads and 0.64mm pitch enable compatibility with automated assembly processes.

GUS-QS8A-02-6801-JB Applications

• Signal Isolation: Precision voltage dividers and feedback networks in op-amp circuits and ADC/DAC interfaces.
• Industrial Controls: PLC I/O modules, sensor conditioning, and power supply feedback loops requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Calibration circuits and reference networks where low TCR minimizes drift.
• Consumer Electronics: Dense PCBs in audio amplifiers or display drivers benefiting from space-saving QSOP packaging.

Conclusion of GUS-QS8A-02-6801-JB

The GUS-QS8A-02-6801-JB excels in applications demanding precision, thermal stability, and compactness. Its thin-film isolation, wide temperature range, and robust QSOP package make it a superior choice over thicker-film or less stable alternatives. While not RoHS-compliant or automotive-grade, it remains a cost-effective solution for industrial and high-reliability consumer designs. Engineers will appreciate its balance of performance, repeatability, and ease of integration in high-density SMT layouts.
