GQ8B011781FAT Description

The GQ8B011781FAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 15-resistor array features a 1.78KΩ resistance value per resistor with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration.
