GQ8A034990GFT Description

The GQ8A034990GFT 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 499Ω 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 configuration and 0.64mm terminal pitch facilitate compact PCB layouts, while the 0.75W total power rating (0.1W per resistor) supports robust performance in demanding circuits. Its isolated (ISOL) circuit design and 100V maximum voltage rating make it suitable for high-reliability environments.

GQ8A034990GFT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±25ppm/°C) for signal conditioning and analog circuits.
• Ceramic QSOP Package: Enhances thermal management and mechanical durability compared to plastic alternatives.
• High Power Density: 0.75W total dissipation (0.1W/resistor) in a compact 4.9mm × 6.02mm × 1.47mm footprint.
• Isolated Resistors: Independent resistors (ISOL design) prevent cross-talk, ideal for multi-channel systems.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, derated for high-temperature environments.
• Gull-Wing Termination: Ensures secure surface mounting with ±0.1mm height tolerance for consistent PCB alignment.
