GUS-QS8B-03-6491-JG Description

The GUS-QS8B-03-6491-JG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount configurations. This 16-pin QSOP package integrates 15 resistors, each with a 6.49KΩ resistance value and a tight ±5% tolerance, ensuring consistent performance across demanding environments. With a 0.75W (3/4W) total power rating and ±25ppm/°C temperature coefficient, this network delivers stable operation under varying thermal conditions (rated for 70°C to 125°C). Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the compact 4.9mm x 6.02mm x 1.47mm footprint optimizes board space.

GUS-QS8B-03-6491-JG Features

• Thin-Film Technology: Offers superior stability, low noise, and precision compared to thick-film alternatives.
• High Power Handling: 0.05W per resistor (total 0.75W) supports robust performance in power-sensitive designs.
• Wide Voltage Range: 100V maximum rating ensures compatibility with industrial and automotive systems (though not PPAP/Automotive certified).
• Thermal Resilience: Operates up to 125°C with derated power capabilities, ideal for high-temperature environments.
• Compact QSOP Package: Rectangular form factor with tight tolerances (±0.1mm height/length) for high-density layouts.
• Non-RoHS Compliant: Suitable for legacy or specialized applications requiring non-compliant materials.

GUS-QS8B-03-6491-JG Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers, feedback networks in op-amp circuits.
• Industrial Controls: PLCs, sensor interfaces, and power management systems requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Calibration circuits, reference networks where low TCR (±25ppm/°C) is critical.
• Legacy Electronics Repair: Non-RoHS compliance makes it a fit for older or niche industrial systems.

Conclusion of GUS-QS8B-03-6491-JG
