GQ8A034702GT Description

The GQ8A034702GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and reliable isolation. This 16-pin QSOP (Quarter Small Outline Package) device features 8 isolated 47KΩ resistors with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across its operating range of -70°C to +125°C. Encased in a ceramic package, it offers superior thermal stability and durability, making it ideal for harsh environments. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this surface-mount (SMD) network is optimized for compact, high-density PCB designs.

GQ8A034702GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistors (ISOL): Each of the 8 resistors is electrically independent, enabling flexible circuit design.
• Ceramic QSOP Package: Enhances thermal dissipation and mechanical robustness compared to plastic alternatives.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• Gull Wing Termination: Ensures secure surface mounting and compatibility with automated assembly processes.
• Low TCR (±25ppm/°C): Minimizes resistance variation under thermal stress, critical for precision applications.
• Compact Dimensions: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length).
