GUS-QS8A-02-3162-DB Description

The GUS-QS8A-02-3162-DB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull wing terminations, this isolated network offers a 31.6KΩ resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation and 0.1W per resistor, it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C. Its 100V maximum voltage rating and thin film technology ensure stable performance in precision circuits.

GUS-QS8A-02-3162-DB Features

• High Precision: ±0.5% tolerance and ±50ppm/°C TCR for critical analog/digital applications.
• Robust Construction: QSOP package (4.9mm x 6.02mm x 1.47mm) with 0.64mm terminal pitch, optimized for dense PCB layouts.
• Isolated Design (ISOL): Each resistor operates independently, reducing crosstalk in signal conditioning.
• Thin Film Technology: Delivers superior stability, low noise, and long-term reliability vs. thick film alternatives.
• Industrial-Grade: Non-automotive (PPAP No) but suited for test equipment, medical devices, and industrial controls.
• Tube Packaging: Protects components during handling and assembly.

GUS-QS8A-02-3162-DB Applications

• Precision Voltage Dividers: Ideal for ADC/DAC reference circuits due to low TCR and tight tolerance.
• Signal Conditioning: Isolated resistors minimize interference in sensor interfaces (e.g., strain gauges, RTDs).
• Medical Electronics: Stable performance in patient monitoring systems and diagnostic equipment.
• Test & Measurement: Calibration circuits and instrumentation requiring repeatable accuracy.
• Power Management: Feedback networks in DC-DC converters, leveraging its 100V rating.

Conclusion of GUS-QS8A-02-3162-DB

The GUS-QS8A-02-3162-DB excels in applications demanding high precision, thermal stability, and compact form factors. Its thin film isolation, robust QSOP package, and industrial-grade specs make it a superior choice over generic resistor arrays. While not RoHS-compliant, it remains a go-to for non-consumer, high-reliability systems where performance outweighs regulatory constraints. Engineers will value its repeatability in harsh environments and seamless integration into space-constrained designs.
