GQ8A032872GT Description

The GQ8A032872GT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it features 28.7KΩ resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The 16-pin gull-wing SMD termination facilitates reliable surface mounting, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for demanding circuits. Its 100V maximum voltage rating and isolated (ISOL) circuit design enhance safety and flexibility in complex layouts.

GQ8A032872GT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±25ppm/°C) for sensitive analog/digital systems.
• Robust Ceramic QSOP Package: Offers superior thermal and mechanical stability compared to plastic alternatives.
• High-Density Integration: 8 resistors in a compact 4.9mm × 6.02mm × 1.47mm footprint, ideal for space-constrained PCBs.
