GUS-QS8A-03-7502-FF Description

The GUS-QS8A-03-7502-FF from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a 16-pin QSOP (Quarter Small Outline Package), this surface-mount device features 75kΩ resistance per resistor with a tight 1% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for signal conditioning, voltage division, and impedance matching. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of -55°C to +125°C, derated from 70°C to 125°C. The gull-wing termination and 0.64mm terminal pitch facilitate robust PCB assembly.

GUS-QS8A-03-7502-FF Features

• Precision Thin Film Technology: Delivers low noise, high stability, and minimal drift over temperature.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
• High Power Density: 0.75W total dissipation in a miniaturized footprint, outperforming similar networks in thermal management.
• Isolated Resistors: Independent 75kΩ resistors enable flexible circuit design without crosstalk.
• Automotive-Grade Alternatives: While not automotive-qualified (PPAP: No), its 125°C max operating temp suits industrial and telecom applications.
• Non-RoHS Compliant: Suitable for legacy or exempted designs requiring leaded components.

GUS-QS8A-03-7502-FF Applications

• Signal Processing: Precision dividers and feedback networks in op-amp circuits.
• Test & Measurement Equipment: Stable reference resistors for calibration.
• Industrial Controls: Isolated bias networks in PLCs and motor drives.
• Telecom Infrastructure: Impedance matching in high-frequency RF modules.
• Medical Devices: Reliable performance in diagnostic instrumentation.

Conclusion of GUS-QS8A-03-7502-FF

The GUS-QS8A-03-7502-FF excels in high-precision, space-constrained applications where thermal stability, isolation, and power efficiency are critical. Its thin-film construction and QSOP packaging offer a superior alternative to bulkier or less stable resistor arrays. While not RoHS-compliant, it remains a top choice for industrial, telecom, and medical systems demanding long-term reliability under harsh conditions. Engineers will appreciate its balance of performance, size, and versatility in complex analog designs.
