GUS-QS8A-02-1690-FF Description

The GUS-QS8A-02-1690-FF from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications in surface-mount PCB assemblies. Encased in a 16-pin QSOP package, this resistor array offers a 169Ω resistance per element with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. Its isolated (ISOL) circuit design allows independent resistor functionality, making it ideal for complex signal conditioning or voltage division tasks. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it balances power handling with compact dimensions (4.9mm x 6.02mm x 1.47mm).

GUS-QS8A-02-1690-FF Features

• Precision Thin Film Technology: Delivers stable performance with low noise and high accuracy (±50ppm/°C).
• Robust Construction: Gull-wing termination and QSOP package ensure reliable surface-mount attachment, compliant with automated assembly processes.
• Isolated Resistor Design: Each of the 8 resistors operates independently, enabling flexible circuit configurations.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C, suitable for harsh environments.
• Compact & Dimensional Precision: Tight tolerances on length (±0.1mm), height (±0.1mm), and depth (±0.2mm) ensure consistent PCB fit.
• Non-Automotive/Non-PPAP: Optimized for industrial and commercial applications where PPAP compliance isn’t required.

GUS-QS8A-02-1690-FF Applications

• Signal Conditioning: Precision voltage division in ADC/DAC circuits or sensor interfaces.
• Medical Electronics: Low-noise amplification stages in diagnostic equipment.
• Test & Measurement: Calibration networks requiring stable resistance values.
• Industrial Controls: Isolated feedback loops in power supplies or motor drives.
• Telecom Infrastructure: Impedance matching in high-frequency RF modules.

Conclusion of GUS-QS8A-02-1690-FF

The GUS-QS8A-02-1690-FF excels in applications demanding high precision, thermal stability, and compact footprint. Its thin-film technology, isolated design, and robust QSOP package make it a superior choice over thicker-film or bulkier alternatives. While not RoHS-compliant, it remains a cost-effective solution for non-automotive, industrial, and instrumentation designs where reliability and accuracy are paramount. Engineers will appreciate its balance of performance, size, and flexibility in complex circuit layouts.
