GQ8A022872GFT Description

The GQ8A022872GFT 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 ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The isolated (ISOL) circuit design allows independent resistor functionality, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Its 16-pin gull-wing SMD termination ensures reliable surface-mount assembly, and the ceramic construction enhances thermal and mechanical durability.

GQ8A022872GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability.
• Isolated Resistor Network: Each of the 8 resistors operates independently, ideal for multi-channel designs.
• Robust Ceramic QSOP Package: Withstands high temperatures and mechanical stress.
• Wide Operating Range: Rated for -55°C to +125°C (derated power up to 125°C).
• Compact Dimensions: 4.9mm (L) x 6.02mm (D) x 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• High Power Density: 0.75W total dissipation in a small footprint.
• Gull-Wing Termination: Ensures secure PCB mounting and solderability.
