GUS-QS8A-03-1872-JB Description

The GUS-QS8A-03-1872-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP package features eight isolated 18.7KΩ resistors with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it offers robust power handling in a compact 4.9mm × 6.02mm × 1.47mm surface-mount package. The gull-wing termination and 0.64mm pitch facilitate reliable PCB assembly, while the 100V maximum voltage rating makes it suitable for medium-voltage circuits.

GUS-QS8A-03-1872-JB Features

• Isolated Resistors (ISOL): Each of the 8 resistors is electrically isolated, enabling flexible circuit design.
• Thin-Film Technology: Delivers low noise, high stability, and tight tolerance (±5%), ideal for precision analog/digital systems.
• High-Temperature Operation: Rated for 125°C maximum operating temperature with derated power up to 125°C, ensuring reliability in harsh environments.
• Compact QSOP Package: Space-saving QSOP-16 form factor with 1.63mm seated height, suitable for high-density PCBs.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) balances performance and thermal management.

GUS-QS8A-03-1872-JB Applications

• Industrial Electronics: Signal conditioning, voltage division, and feedback networks in control systems.
• Test & Measurement Equipment: Precision reference circuits and calibration modules.
• Medical Devices: Low-drift analog front-ends where stability is critical.
• Automotive (Non-Automotive Rated): Non-safety-critical circuits like sensor interfaces (note: not PPAP/automotive compliant).
