GQ8A031740GT Description

The GQ8A031740GT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it offers a 174Ω resistance per element with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. Rated for 0.1W (1/10W) per resistor and 0.75W (3/4W) total power dissipation, it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. Its 16-pin gull-wing SMD termination ensures secure surface mounting, while the ceramic construction enhances thermal stability and durability.

GQ8A031740GT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±25ppm/°C) for sensitive circuits.
• Isolated Resistor Network (ISOL): Each resistor operates independently, ideal for multi-channel isolation.
• Robust Ceramic Package: Superior heat dissipation and mechanical strength compared to plastic alternatives.
• Compact QSOP-16 Footprint: Space-saving design (4.9mm × 6.02mm × 1.47mm) with ±0.1mm dimensional tolerances.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its 125°C max operating temperature suits industrial environments.
• Non-RoHS Compliance: Suitable for legacy or specialized applications requiring non-RoHS materials.

GQ8A031740GT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers in instrumentation and sensor interfaces.
