GUS-QS8A-03-4701-FB Description

The GUS-QS8A-03-4701-FB from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a 16-pin QSOP package with gull wing termination, this surface-mount device offers a 4.7KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a 70°C to 125°C derated power range, peaking at 125°C. The compact 4.9mm x 6.02mm x 1.47mm footprint and 0.64mm terminal pitch enable high-density PCB layouts.

GUS-QS8A-03-4701-FB Features

• Precision Thin Film Technology: Delivers stable performance with ±25ppm/°C TCR and 1% tolerance for critical analog circuits.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) supports higher current applications than standard arrays.
• Isolated Design (ISOL): Each resistor operates independently, eliminating cross-talk in multi-channel systems.
• High-Temperature Resilience: Rated for 125°C maximum operating temperature, suitable for industrial environments.
• Compact QSOP Package: 16-pin gull wing SMD with ±0.1mm height/length tolerances ensures compatibility with automated assembly.
• Non-Automotive (PPAP No): Optimized for industrial, telecom, and instrumentation use.

GUS-QS8A-03-4701-FB Applications

• Signal Conditioning: Precision voltage dividers in sensor interfaces (e.g., thermocouples, strain gauges).
• Medical Electronics: Isolated feedback networks in patient monitoring equipment.
• Test & Measurement: Calibration circuits requiring low TCR and high stability.
• Industrial Controls: PLCs and motor drives where temperature fluctuations are common.
• Telecom Infrastructure: Line termination and impedance matching in high-frequency modules.

Conclusion of GUS-QS8A-03-4701-FB

The GUS-QS8A-03-4701-FB excels in applications demanding precision, thermal stability, and compactness. Its isolated thin film resistors, high power rating, and QSOP form factor make it a superior alternative to bulkier or less stable networks. While not RoHS-compliant, its EAR99/ECCN classification ensures broad exportability. Engineers will value its reliability in harsh environments and space-constrained designs, particularly in industrial, medical, and telecom systems.
