GUS-QS8A-03-2102-GF Description

The GUS-QS8A-03-2102-GF from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications. This 21K Ohm, 2% tolerance thin-film resistor array features a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Housed in a 16-pin QSOP (QSOP-16) package, it offers a compact 4.9mm x 6.02mm footprint with gull-wing SMD termination, making it ideal for space-constrained PCB designs. The 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating provide robust handling of distributed loads, while the 100V maximum voltage rating ensures reliability in high-voltage circuits.

GUS-QS8A-03-2102-GF Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Network (ISOL): Each resistor operates independently, eliminating crosstalk in multi-channel systems.
• High-Temperature Resilience: Rated for 125°C maximum operating temperature, suitable for industrial and automotive environments (though non-PPAP).
• Tight Tolerances: ±2% resistance tolerance and ±25ppm/°C TCR ensure consistent performance.
• Optimized Mechanical Design: 0.64mm terminal pitch and 1.47mm profile enable high-density SMT assembly.
• Non-RoHS Compliant: Suitable for legacy or specialized applications requiring non-RoHS materials.

GUS-QS8A-03-2102-GF Applications

• Signal Conditioning: Precision voltage dividers, ADC/DAC reference networks.
• Industrial Controls: Isolated feedback loops in motor drives, power supplies.
• Test & Measurement Equipment: Calibration circuits, sensor interfaces.
• Telecom Infrastructure: Line termination, impedance matching in high-frequency PCBs.
• Medical Devices: Low-drift circuits where stability is critical.

Conclusion of GUS-QS8A-03-2102-GF

The GUS-QS8A-03-2102-GF excels in applications demanding precision, isolation, and thermal resilience. Its thin-film construction, tight tolerances, and compact QSOP package make it a superior choice over thicker-film or bulkier alternatives. While not automotive-grade, its 125°C rating and 100V capability cater to harsh industrial environments. Engineers will value its reliability in signal integrity-critical designs, particularly where board space and performance are prioritized.
