GUS-QS8B-03-3901-JG Description

The GUS-QS8B-03-3901-JG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 3.9K Ohm resistance value and a tight ±5% tolerance, ensuring consistent performance across batches. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it balances power dissipation and compactness, making it ideal for space-constrained designs. The thin-film technology delivers excellent stability, with a low ±25ppm/°C temperature coefficient, minimizing resistance drift over temperature fluctuations (70°C to 125°C derated range). Its gull-wing termination and surface-mount design facilitate automated assembly, while the 100V maximum voltage rating ensures reliability in high-voltage environments.

GUS-QS8B-03-3901-JG Features

• High-Density Integration: 15 resistors in a compact QSOP-16 package (4.9mm x 6.02mm x 1.47mm) with ±0.1mm length/height tolerances.
• Precision Performance: ±5% tolerance and ±25ppm/°C TCR for stable operation in temperature-variable environments.
• Robust Power Handling: 0.75W total power (0.05W per resistor) and 125°C maximum operating temperature.
• Automation-Friendly: Gull-wing leads with 0.64mm pitch for reliable surface-mount soldering.
• Wide Compatibility: Suitable for industrial and commercial applications, though not PPAP or automotive-qualified.
• Non-RoHS (Not compliant with EU RoHS), ideal for legacy or exempted systems.

GUS-QS8B-03-3901-JG Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers, feedback networks in op-amp circuits.
• Digital Systems: Pull-up/pull-down resistor arrays for buses (e.g., I²C, SPI) or microcontroller I/O lines.
• Test & Measurement Equipment: Stable reference networks in multimeters or calibration tools.
• Power Management: Current-limiting or balancing in low-power DC/DC converters.
• Industrial Controls: Durable performance in PLCs, sensor interfaces, and motor drivers.
