GUS-QS0B-03-5101-DD Description

The GUS-QS0B-03-5101-DD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 5.1KΩ resistance, a tight 0.5% tolerance, and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C derated power range. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network excels in precision analog and digital circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the compact 8.66mm × 6.02mm × 1.47mm footprint saves board space.

GUS-QS0B-03-5101-DD Features

• High Precision: 0.5% tolerance and ±25ppm/°C TCR for stable performance in temperature-variable environments.
• Robust Construction: Thin-film technology ensures low noise and high reliability.
• Space-Efficient: QSOP package (20-pin) with a 1.63mm seated height suits high-density layouts.
• Wide Operating Range: -55°C to 125°C (derated to 70°C–125°C) for industrial and automotive-grade applications (note: non-automotive PPAP).
• Optimized Power Handling: 1W total dissipation (0.05W/resistor) balances performance and thermal management.

GUS-QS0B-03-5101-DD Applications

Ideal for precision circuitry requiring matched resistors, such as:

• Voltage dividers and ADC/DAC reference networks in test equipment.
• Signal conditioning in medical devices and instrumentation.
• Feedback networks for op-amps in industrial control systems.
• Impedance matching in communication hardware.
  The non-RoHS status may limit use in EU-regulated applications but suits legacy or specialized systems.
