GUS-QS8A-03-2610-JB Description

The GUS-QS8A-03-2610-JB from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications in surface-mount circuits. Encased in a 16-pin QSOP package with gull-wing terminations, this device offers a 261Ω resistance per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Its isolated (ISOL) circuit design allows independent resistor functionality, making it ideal for complex circuit configurations. The 0.75W (3/4W) total power rating and 100V maximum voltage rating provide robust handling of moderate power loads in compact designs.

GUS-QS8A-03-2610-JB Features

• Thin-film technology: Delivers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• High-density QSOP package: Compact dimensions (4.9mm × 6.02mm × 1.47mm) with a 0.64mm terminal pitch enable space-efficient PCB layouts.
• Wide temperature range: Reliable operation from -70°C to +125°C, suitable for industrial and automotive-adjacent environments (though not PPAP or Automotive-qualified).
• Isolated resistors: Each of the 8 resistors operates independently, offering design flexibility for signal conditioning, pull-up/down networks, or voltage division.
• Robust power handling: 0.1W per resistor (0.75W total) derated at elevated temperatures, ensuring durability in high-stress conditions.

GUS-QS8A-03-2610-JB Applications

This resistor network excels in:

• Precision analog circuits: Voltage dividers, feedback networks, and sensor interfaces where low TCR (±25ppm/°C) is critical.
• Signal isolation: Isolated signal paths in communication modules, ADC/DAC circuits, and mixed-signal PCBs.
• Industrial electronics: Control systems, power management, and instrumentation requiring stable performance under thermal cycling.
• Consumer electronics: Dense PCB designs in audio equipment, display drivers, or power supplies benefiting from its compact footprint.
