GUS-QS8A-03-7500-JA Description

The GUS-QS8A-03-7500-JA from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a compact 16-pin QSOP package with gull-wing SMD termination, it offers a 750Ω resistance per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The device supports a maximum voltage rating of 100V and delivers a total power rating of 0.75W (0.1W per resistor), making it suitable for demanding circuits requiring isolation (denoted by "ISOL" circuit designator). Its thin-film technology provides superior accuracy and reliability compared to thick-film alternatives.

GUS-QS8A-03-7500-JA Features

• High Precision: ±25ppm/°C TCR and 5% tolerance ensure minimal drift in critical applications.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) at derated temperatures up to 125°C.
• Compact & Durable: QSOP package (4.9mm × 6.02mm × 1.47mm) with tight tolerances (±0.1mm height/length, ±0.2mm depth) for space-constrained designs.
• Isolated Resistors: Independent resistors (non-bussed) for flexible circuit design.
• Surface-Mount Ready: Gull-wing terminals with 0.64mm pitch for easy PCB assembly.
• Wide Compatibility: Suitable for industrial and commercial (non-automotive) applications.

GUS-QS8A-03-7500-JA Applications

Ideal for:

• Signal conditioning in data acquisition systems.
• Voltage division and impedance matching in communication hardware.
• Isolation networks in test and measurement equipment.
• Precision analog circuits where low TCR and tight tolerance are critical.
• Medical devices and industrial controls requiring stable performance under thermal stress.

Conclusion of GUS-QS8A-03-7500-JA

The GUS-QS8A-03-7500-JA excels in applications demanding high precision, thermal stability, and compact form factors. Its thin-film construction, isolated resistors, and robust power handling make it a superior choice over generic resistor arrays. While not RoHS-compliant or PPAP-qualified, it remains a reliable solution for non-automotive industrial electronics, particularly where space and performance are paramount.
