GUS-QS8B-02-3302-J Description

The GUS-QS8B-02-3302-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features 15 resistors with a 33K Ohm resistance value, a 5% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in demanding circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density mounting, while the compact 4.9mm x 6.02mm x 1.47mm footprint optimizes space efficiency.

GUS-QS8B-02-3302-J Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent thermal stability compared to thick-film alternatives.
• High Power Handling: 0.75W total rating (distributed across 15 resistors) supports robust operation in power-sensitive designs.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power, ideal for industrial and automotive environments (though not PPAP/Automotive certified).
• Compact QSOP Package: 16-pin gull-wing SMD design with 1.63mm seated height ensures compatibility with automated assembly processes.
• Low TCR (±50ppm/°C): Minimizes resistance drift under thermal stress, critical for precision analog and signal conditioning circuits.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.

GUS-QS8B-02-3302-J Applications

This resistor network excels in:

• Voltage Divider Networks: Precision attenuation in sensor interfaces or ADC front-ends.
• Bus Termination: Stable impedance matching for BUS lines in digital communication systems (e.g., SPI, I²C).
• Industrial Control Systems: Durable performance in PLCs, motor drives, and power supplies.
• Test & Measurement Equipment: Low-drift resistance for calibration circuits and signal generators.
• Legacy Electronics Repair: Direct replacement for non-RoHS compliant designs.
