GQ8A032672GFT Description

The GQ8A032672GFT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor network features a 26.7K Ohm resistance per element with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a 70°C to 125°C operating range. Housed in a ceramic QSOP package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and supports 100V maximum voltage rating, making it suitable for high-voltage isolation circuits. The 16-pin gull-wing SMD termination ensures secure surface mounting, while the ±0.1mm height/length tolerances and 1.47mm profile enable compact PCB integration.
