GUS-QS8A-03-1370-JC Description

The GUS-QS8A-03-1370-JC from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding environments. This 8-resistor isolated network features a 137 Ω resistance value per resistor with a 5% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Encased in a compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and supports a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the tube packaging ensures safe handling and storage.

GUS-QS8A-03-1370-JC Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent thermal stability compared to thick-film alternatives.
• High Power Density: 0.75W total power rating in a compact 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint, ideal for space-constrained designs.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power, suited for industrial and automotive-adjacent applications.
• Isolated Circuit Design (ISOL): Each resistor is electrically isolated, enabling flexible circuit configurations.
• Robust Construction: QSOP package with 1.63mm seated height and 0.64mm terminal pitch ensures mechanical durability and solderability.

GUS-QS8A-03-1370-JC Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring tight tolerance and low TCR.
• Industrial Control Systems: PLCs, motor drives, and power supplies where high-temperature stability is critical.
• Telecommunications Equipment: Signal conditioning and impedance matching in RF modules and base stations.
• Medical Electronics: Diagnostic devices and portable monitors demanding reliable performance in compact layouts.
• Automotive-Adjacent Systems: Although not PPAP/automotive-certified, it suits non-safety-critical applications like infotainment or lighting controls.

Conclusion of GUS-QS8A-03-1370-JC

The GUS-QS8A-03-1370-JC stands out for its thin-film precision, isolated design, and robust power handling in a miniaturized form factor. Its ±25 ppm/°C TCR and 5% tolerance make it a cost-effective choice for applications demanding stability without ultra-high precision. While not RoHS-compliant or automotive-grade, its 125°C maximum operating temperature and 100V voltage rating ensure reliability in industrial and telecom environments. Engineers will appreciate its balance of performance, size, and versatility for densely populated PCBs.
