GUS-QS8A-02-1781-CA Description

The GUS-QS8A-02-1781-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 1.78KΩ resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating and 100V maximum voltage rating provide robust handling of moderate power loads while maintaining reliability.

GUS-QS8A-02-1781-CA Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), saving PCB space in dense layouts.
• Gull Wing Termination: Ensures reliable surface-mount soldering with a 0.64mm terminal pitch for automated assembly.
• Derated Power Handling: Maintains performance up to 125°C with derated power capabilities.
• Non-Automotive, Non-PPAP: Optimized for industrial and commercial applications where PPAP compliance is not required.

GUS-QS8A-02-1781-CA Applications

This resistor network excels in precision-critical applications such as:

• Medical Instrumentation: High-accuracy sensor interfaces and signal conditioning.
• Test & Measurement Equipment: Voltage dividers, calibration circuits, and reference networks.
• Industrial Control Systems: Isolated feedback loops and analog signal processing.
• Communications Hardware: RF matching networks and impedance stabilization.
  Its non-RoHS status may limit use in EU-regulated applications but is advantageous where leaded soldering is preferred.
