GQ8A029101FT Description

The GQ8A029101FT 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 9.1K Ohm resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 16-pin gull-wing SMD configuration offers reliable surface-mount compatibility, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its isolated (ISOL) circuit design provides flexibility in signal routing, and the ceramic case enhances thermal and mechanical durability.

GQ8A029101FT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±50ppm/°C).
• Robust Ceramic Package: Superior heat dissipation and mechanical strength vs. plastic alternatives.
• High-Density QSOP (6.02mm x 4.9mm): Saves PCB space while supporting 8 isolated resistors.
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated power up to 125°C).
• Gull-Wing Termination: Ensures secure SMD soldering and vibration resistance.
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and test equipment where extreme precision is critical.
