GUS-QS8A-01-1691-JB Description

The GUS-QS8A-01-1691-JB is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications requiring stable resistance values and compact packaging. This 16-pin QSOP (Quarter Small Outline Package) device features 8 isolated resistors, each with a 1.69 kΩ resistance value, a 5% tolerance, and a ±100 ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a temperature range of 70°C to 125°C, making it suitable for demanding environments. The gull-wing termination ensures secure surface-mount (SMD) assembly, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) save PCB space.

GUS-QS8A-01-1691-JB Features

• Thin-film technology for superior stability and low noise.
• Isolated circuit design (ISOL) for independent resistor functionality.
• High power handling (0.75W total, 0.1W per resistor) in a miniature QSOP package.
• Wide operating temperature range (-70°C to +125°C) with derated performance up to 125°C.
• Gull-wing SMD termination for robust soldering and mechanical reliability.
• 100V maximum voltage rating, suitable for industrial and instrumentation use.
• Tube packaging for automated pick-and-place assembly.

GUS-QS8A-01-1691-JB Applications

This resistor network is ideal for:

• Precision analog circuits requiring stable resistance values (e.g., signal conditioning, feedback networks).
• Industrial control systems where temperature stability and compactness are critical.
• Medical electronics due to its low noise and reliability.
• Automotive test equipment (though not automotive-grade, its performance suits prototyping and bench testing).
• Embedded systems where space-efficient, multi-resistor solutions are needed.

Conclusion of GUS-QS8A-01-1691-JB

The GUS-QS8A-01-1691-JB excels in applications demanding miniaturization, thermal stability, and precise resistance matching. Its thin-film construction, isolated resistors, and robust QSOP package make it a superior choice over thicker-film or less stable alternatives. While not PPAP or automotive-qualified, its high power density and wide temperature range ensure reliability in industrial, medical, and test equipment. Engineers will appreciate its balance of performance, size, and cost for high-density PCB designs.
