GUS-QS8A-03-7150-DB Description

The GUS-QS8A-03-7150-DB is a high-precision 8-resistor isolated network from TT Electronics/IRC, designed for demanding surface-mount applications. Featuring a 715Ω resistance value with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, this thin-film resistor network ensures stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing terminations, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it ideal for space-constrained, high-reliability circuits. Its 100V maximum voltage rating and isolated (ISOL) circuit design enhance safety and signal integrity in complex systems.

GUS-QS8A-03-7150-DB Features

• Precision Thin Film Technology: Delivers superior accuracy (±0.5%) and low TCR (±25ppm/°C) for stable operation in varying environments.
• Robust Power Handling: Supports 0.75W total dissipation (0.1W per resistor), outperforming standard networks in power density.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for high-density PCB layouts.
• Isolated Design (ISOL): Each resistor is electrically isolated, reducing crosstalk in multi-channel applications.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power, suited for industrial and automotive-grade designs (though not PPAP/automotive-certified).
• Gull-Wing SMD Termination: Ensures secure soldering and mechanical stability in vibration-prone environments.

GUS-QS8A-03-7150-DB Applications

• Signal Conditioning: Precision voltage dividers and feedback networks in instrumentation and sensor interfaces.
• Medical Electronics: Isolated resistor networks for patient monitoring equipment, ensuring signal integrity.
• Industrial Control Systems: High-temperature environments like motor drives or power supplies, where stability is critical.
• Communications Infrastructure: RF and analog circuitry requiring low TCR and minimal drift over time.
• Test & Measurement Equipment: Calibration circuits and reference networks demanding sub-1% tolerance.
