GUS-QS8A-03-1690-CC Description

The GUS-QS8A-03-1690-CC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package features 8 isolated resistors, each with a 169Ω resistance value and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of -70°C to +125°C. The device supports a maximum voltage rating of 100V and offers a total power dissipation of 0.75W (3/4W), with 0.1W (1/10W) per resistor, making it suitable for compact, high-density PCB designs.

GUS-QS8A-03-1690-CC Features

• Precision Thin-Film Technology: Ensures low noise, high stability, and repeatable performance in critical circuits.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, eliminating crosstalk in multi-channel systems.
• Robust Power Handling: 0.75W total power rating (0.1W per resistor) with derating up to 125°C.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained applications.
• Gull Wing Termination: Facilitates reliable surface-mount assembly with a 0.64mm terminal pitch for automated PCB placement.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, suited for industrial and automotive environments (though not PPAP/Automotive certified).

GUS-QS8A-03-1690-CC Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and DAC/ADC interfaces requiring tight tolerance.
• Medical Electronics: Patient monitoring equipment where signal integrity is critical.
• Test & Measurement Systems: Calibration tools and sensor signal conditioning.
• Industrial Controls: PLCs, motor drives, and power supplies demanding stable performance under thermal stress.
• Communications Infrastructure: RF matching networks and filter circuits in base stations.

Conclusion of GUS-QS8A-03-1690-CC

The GUS-QS8A-03-1690-CC stands out for its precision, isolation, and power efficiency in a miniaturized QSOP footprint. Its thin-film construction and low TCR make it superior to thick-film alternatives in applications requiring long-term stability. While not RoHS-compliant, it remains a top choice for non-consumer industrial designs where reliability outweighs regulatory constraints. Engineers will appreciate its balance of performance, size, and cost for high-accuracy analog systems.
