GUS-QS8A-02-5111-BB Description

The GUS-QS8A-02-5111-BB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 5.11 kΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50 ppm/°C temperature coefficient, it delivers stable performance across a wide operating range (-70°C to +125°C). The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for high-reliability environments.

GUS-QS8A-02-5111-BB Features

• Precision Thin Film Technology: Offers low noise and high stability for critical analog circuits.
• Isolated Resistor Design (ISOL): Each of the 8 resistors operates independently, reducing crosstalk.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained PCBs.
• Gull Wing Termination: Ensures robust solder joints for surface-mount assembly.
• Derated Power Handling: Maintains 0.1W per resistor even at elevated temperatures (up to 125°C).
• Tube Packaging: Protects components during shipping and automated placement.

GUS-QS8A-02-5111-BB Applications

This resistor network excels in:

• Precision Instrumentation: Medical devices, test equipment, and data acquisition systems requiring <0.1% tolerance.
• Industrial Controls: PLCs, motor drives, and sensor interfaces where temperature stability (±50ppm/°C) is critical.
• Telecommunications: RF modules and signal processing circuits benefiting from low parasitic effects.
• Automotive & Aerospace (Non-PPAP): Non-safety-critical systems needing high-density resistance solutions.

Conclusion of GUS-QS8A-02-5111-BB

The GUS-QS8A-02-5111-BB stands out for its combination of precision, isolation, and power handling in a miniaturized QSOP format. Its thin-film construction and tight tolerances make it superior to thick-film alternatives in noise-sensitive or thermally variable environments. While not PPAP-compliant, it remains a cost-effective choice for industrial and telecom applications demanding reliability without automotive certification. Engineers will appreciate its balance of performance and footprint efficiency.
